Adelaide United 

A poor season last year prompted the injection of a new coach by the Reds and they've already seen an improvement on last year's form.

After conceding a below average 46 goals from 27 games last season, Kurz has installed a more sound defensive structure in the preseason which has only seen them concede two goals from seven matches including three against A-League opponents.

Former Turkish international Ersan Gulum is one inclusion that will help shore up their defence while an array of young talent is ready to be unleashed on the league this season.

While they have improved in an array of areas around the park, the Reds have lost a significant amount of experience which have the potential to hurt their quest to return to the A-League finals.

Several question marks remain over Adelaide's season, however, in a short space of time, it appears as though Kurz has done a good job in getting his squad to buy into his philosophy.

Coach: Marco Kurz

Last season: 9th (5-8-14)

Ins: Paul Izzo, George Blackwood, Ersan Gulum, Johan Absalonsen, Vince Lia, Karim Matmour

Outs: Dylan McGowan, George Mells, Sergio Cirio, John Hall, Jesse Makarounas, Eugene Galekovic, Kim Jae-sung, Marcelo Carrusca , Iacopo La Rocca, Riley McGree, Eli Babalj

Newcastle Jets 

Generally after finishing at the foot of the table, a major clean out is required and that is exactly what has happened at the Jets this winter.

Ernie Merrick has stepped in as head coach and overhauled the squad that won just five matches last season by bringing in players that can draw on a wealth of experience as they look to climb the A-League ladder.

Venezuelan international Ronny Vargas has come on board to help boost their attack which managed just 28 goals last campaign as he joins fellow newcomer Roy O'Donovan up front.

Defensively, their veteran additions should help shore up their fragility at the back while Dimi Petratos will join young gun Steven Urgakovic in the middle of the park in a position that should thrive under Merrick's regime.

It's been eight long years since the Jets have seen post-season action, could Merrick's championship experience take them back to finals football?

Coach: Ernie Merrick

Last Season: 10th (5-7-15)

Ins: Daniel Georgievski, Mario Shabow, Roy O'Donovan, Kosta Petratos, Glen Moss, Dimitri Petratos, Nikolai Topor-Stanley, Jake Adelson, Ronny Vargas

A new-look Brisbane side will enter season 2017/18 after they were just 20 minutes away from a grand final last season.

Several big names have departed John Aloisi's side while a number of experienced heads will don their iconic orange jersey this season as they look to challenge Sydney FC for the league's top mantle.

All eyes will be on their revamped attack as the experienced Fahid Ben Khalfallah, Eric Bautheac and Massimo Maccarone will headline their forward half. That will be one of the major challenges that Aloisi faces in the opening weeks of the season as the players at his disposal play a significantly different style to those who he had last year.

Nick D'Agostino will also play a key part in attack for the Roar with the 19-year-old set for a breakout season.

Coach: John Aloisi

Last season: 3rd (15-4-8)

Ins: Fahid Ben Khalfallah, Corey Gameiro, Massimo Maccarone, Mitch Oxborrow, Emilio Martinez, Petros Skapetis, Eric Bautheac.

Outs: Thomas Broich, Brandon Borrello, Jamie Maclaren, Manuel Arana, Cameron Crestani, Joey Katebian, Nathan Konstandopoulos, Tommy Oar, Kye Rowles.

Central Coast Mariners

The Mariners will enter the 2017/18 A-League season as one of the more exciting teams to watch following a host of youthful inclusions into their squad.

Their eighth place finish last season saw them some 13 points and 21 goals out of the finals conversation and the additions of Daniel De Silva, Alan Baro and Andrew Hoole will give fans plenty of promise heading into the new campaign.

Tom Hiariej and Wout Brama will add some much needed stability in their midfield and De Silva's return to the A-League to link up with his former youth coach will be a tantalising prospect for Mariners fans.

Alan Baro has already proven to be a valuable pick up for the side with Okon handing the 32-year-old the captains armband for the season ahead.

Coach: Paul Okon

Last season: 8th (6-5-15)

Ins: Tom Hiariej, Alan Baro, Antony Golec, Andrew Hoole, Ben Kennedy, Kye Rowles, Josh Rose, Daniel De Silva, Thomas Glover, Asdrúbal, Wout Brama.

Outs: Paul Izzo, Roy O’Donovan, Fabio Ferreira, Ivan Necevski, Nick Montgomery, Jacob Poscoliero, Jacques Faty, Scott Galloway, Mickael Tavares, Michael Neill, Jake Adelson.

It's never easy losing the captain of your club in the off-season but Kenny Lowe has managed to recruit a number of quality players that can keep the Glory in contention come the back end of the season.

Consistency plagued their campaign last time around and potentially cost them going deeper into the finals series. They start the season with three of the first four games on the road which will be a challenge for the squad first up.

Their away form left a lot to be desired last season and that's one area they simply must improve on this year. Their front third remains extremely potent and have added highly-rated attacker Xavi Torres however it's their defence that requires tightening to see them climb the A-League ladder.

They had the equal-worst defence last season and with the departures of key defensive personnel in Dino Djulbic and Rhys Williams, they could still yet have a few headaches at that end of the park.

19-year-old Jake Brimmer looks set for a breakout year and after being released from the Liverpool academy, the two-way midfielder could prove a key link man in the upcoming season.

Coach: Kenny Lowe

Last season: 5th (10-9-8)

Ins: Scott Neville, Jacob Poscoliero, Joe Knowles, Mitch Nichols, Jake Brimmer, Andreu Guerao, Xavi Torres, Daniel Stynes.

Outs: Dino Djulbic, Kosta Petratos, Richard Garcia, Josh Risdon, Aryn Williams, Rhys Williams, Lucian Goian, Nebojsa Marinkovic, Mitchell Oxborrow, Jordan Thurtell, Rostyn Griffiths.

Western Sydney Wanderers 

The Wanderers has made a number of impressive decisions in the off-season however Tony Popovic's recent and surprise departure has thrown the club's plans into chaos on the eve of the season.

A big clean out of their squad was needed to propel them into championship contention and the signings of several big names including former Barcelona academy player Oriel Riera will have fans licking their lips ahead of the new season.

"He showed an amazing work rate. You can see the team is trying to get to know him and he is trying to get to know the players," former coach Popovic said of Riera.

Their biggest problem last season was in attack and the likes of Roly Bonevacia, Alvaro Cejudo and Marc Tokich should help boost their goal-scoring tally in 2017/18.

A big season is in store for the side which took the A-League by storm in their early years and if they're able to quickly overcome the loss of their coach, it will show they're a force to be reckoned with.

Coach: Hayden Foxe (caretaker)

Last season: 6th (8-12-7)

Ins: Josh Risdon, Michael Thwaite, Roly Bonevacia, Abraham Majok, John Hall, Nicholas Suman, Oriol Riera, Marc Tokich, Mark Bridge, Álvaro Cejudo, Chris Herd, Raúl Llorente.

Outs: Dimas, Mitch Nichols, Scott Neville, Bruno Piñatares, Ryan Griffiths, Liam Youlley, Stefan Zinni, Emilio Martinez, Nicolás Martinez, Terry Antonis, Shannon Cole, Mario Shabow, Jackson Bandiera, Aritz Borda.

Melbourne City

Another side with a number of changes in the off-season, Melbourne City has recruited impressively with a number of big names joining the squad.

Former Aston Villa and Scottish international striker Ross McCormack is the most notable of the names however his inclusion comes at the expense of superstar striker Bruno Fornaroli who is out for a number of months due to injury.

Consistency has been a major problem for City in recent seasons and their defensive personnel has often been questioned by fans. One player who should help instil some solidarity is youngster Ruon Tongyik. The 20-year-old made his debut for the side last year and has enormous potential and a big season this summer will see his stocks rise tremendously.

City's new coach, like the rest of us, has seen the squad's lack of depth in certain areas and has put together a squad which won't solely rely on their stars. Should they find a consistent brand of football, they should be able to match it with the big clubs in the league.

Coach: Warren Joyce

Last season: 4th

Ins: Eugene Galekovic, Scott Jamieson, Iacopo La Rocca, Stefan Mauk, Bart Schenkeveld, Marcelo Carrusca, Marcin Budzinski, Ross McCormack.

Outs: Corey Gameiro, Steve Kuzmanovski, Josh Rose, Nicolas Colazo, Thomas Sorensen, Paulo Retre, Ivan Franjic, Anthony Caceres,

Wellington Phoenix

A new logo, a new coach and a new look roster for the Phoenix will see them through the 2017/18 season as they look to turn their recent form around.

Dario Vidosic returns to the A-League and should provide a certain amount of poise and class as an attacking midfielder while combining with new striker Andrija Kaludjerovic. Ali Abbas and Scott Galloway will strengthen the club's defensive stocks in a club that has lost a wealth of experience in the off-season.

Wellington's list isn't the most eye-catching in the league and it could prove that way on the park this season however with a fresh coaching ideas from the highly rated Kalezic, there will be a sense of optimism around the club.

Coach: Darije Kalezic

Last season: 7th (8-6-13)

Ins: Scott Galloway, Goran Paracki, Dario Vidosic, Daniel Mullen, Andrija Kaludjerovic, Ali Abbas.

Outs: Roly Bonevacia, Shane Smeltz, Jacob Tratt, Glen Moss, Kosta Barbarouses, Alex Rodriguez, Vince Lia.

Melbourne Victory

The A-League heavyweights will head into the new campaign with sky high expectations as they look to go one better after last season's heartbreaking end.

The additions of Rhys Williams and Kosta Barbarouses will help strength either end of the park while imports Matias Sanchez and Leroy George as well as Mark Milligan's return will ensure competition for spots is at an all-time high in midfield.

They open the season with three huge rivalries against Sydney, City and Adelaide however Socceroos duties could hurt the side significantly over the course of the season, starting this week in the grand final rematch.

Melbourne will continue to play a similar high-pressure brand of football and with their loaded midfield talent, that will be made more possible.

Limits will not be put on the Victory season and as always, their league-leading fan base will expect the world from Muscat as his squad.

Coach: Kevin Muscat

Last season: 2nd (15-4-8)

Ins: Rhys Williams, Kosta Barbarouses, Matias Sanchez, Leroy George, Mark Milligan

Outs: Fahid Ben Khalfallah, Daniel Georgievski, Nick Ansell, Alan Baro, Alistair Bray, George Howard, Lucas Spinella, Marco Rojas.

Sydney FC

There was simply no match for Sydney last season and they'll look to replicate the feats achieved in 2016/17 by becoming the second side in A-League history to go back-to-back.

Much of last season's squad remains in place and while key attacker Filip Holosko has departed along with shot stopper Danny Vukovic, they'll be expecting to finish on top of the pack once finals rolls around.

Defensively, they were unbelievable last season (conceding just 13 goals and there's not much to suggest too much will change in that department this season while their midfield once again looks to be a strength with Polish international Adrian Mierzejewski joining Milos Ninkovic in the middle third of the field.

Bobo and Alex Brosque will continue to lead the front line as they simple look to build a strong base from the outset with Asian Champions League action to look forward to throughout the season.

Coach: Graham Arnold

Ins: Paulo Retre, Alex Cisak, Luke Wilkshire, Chris Zuvela, Adrian Mierzejewski, Anthony Kalik
