1. Sydney F.C

Last Week's Ranking: 1 

The Sky Blues remain top of the power rankings after asserting their A-League dominance with a 2-1 win over the previously undefeated Jets.

Sitting top of the tree with 16 points from the opening seven games, Sydney are the red-hot favourites to win back-to-back titles, showing no signs of slowing down.

Brazilian striker Bobo has struck good form, assisting the opener and then finding the back of the net himself in the pivotal victory over Newcastle.

Next Opponent: Brisbane Roar (H)

2. Newcastle Jets

Last Week's Ranking: 2

The Jets remain the second best side in the competition after putting in a valiant effort in the hardest away fixture in A-League football against Sydney F.C.

Melbourne City's rough patch of form ensures the Jets keep their spot in the power rankings and on the A-League table, with just the one loss for season 2017/18 to date.

Dimitri Petratos' stunning campaign continued with an impressive goal from distance to beat the Sydney defence, further pressing his claim for a 2018 World Cup berth in the Socceroos squad.

Next Opponent: Melbourne Victory (H)

3. Melbourne City

Last Week's Ranking: 3

Melbourne City are clinging onto their position in the rankings only thanks to the lack of competition below them, after losing two of their last three contests, with a draw in between.

City's rock-solid defensive unit has looked penetrable over the last three weeks, conceding five goals in that time compared with one over their first four fixtures.

Tim Cahill's possible Round 8 return will be a much-needed boost against the Glory.

Next Opponent: Perth Glory (H)

4. Western Sydney Wanderers

Last Week's Ranking: 4

The Wanderers keep their spot by default after their home fixture against the Phoenix was postponed due to poor pitch conditions.

The match-up would have presented the perfect opportunity for the Wanderers to break their streak of draws with a victory and climb up the rankings, with Wellington struggling greatly away from New Zealand.

Next Opponent: Adelaide United (A)

5. Melbourne Victory

Last Week's Ranking: 8

The Victory rise three spots with their first win of the campaign, an impressive 2-0 victory in Perth.

The heat was on Melbourne to secure their first three points of the season after fellow win-less club Brisbane won earlier in the round, and it was again Berisha that broke the game open with a 56th minute goal.

Lawrence Thomas and Rhys Williams had superb performances, keeping a clean sheet, while Mark Milligan controlled the midfield only four days after representing the Socceroos in Sydney.

Huge match-up in Newcastle on Thursday night.

Next Opponent: Newcastle Jets (A)

6. Adelaide United

Last Week's Ranking: 9

The Reds are another significant riser after Round 7's action, overcoming an in-form Mariners side on the road 2-1.

United now sit fifth on the A-League standings despite losing three straight games prior to their away win, such is the close proximity of the lower end of the ladder.

Jordan Elsey, Daniel Adlung and Karim Matmour starred in the return-to-form triumph.

They face Sydney F.C in the FFA Cup final tonight at Allianz Stadium, before hosting the well-rested Wanderers on Sunday night.

Next Opponent: Western Sydney Wanderers (H)

7. Central Coast Mariners

Last Week's Ranking: 5

The Mariners are a Round 7 slider after a disappointing home loss to Adelaide.

Central Coast went up 1-0 late in the first half thanks to a penalty from Wout Brama, but were unable to hold onto their lead, conceding in the 59th and 93rd minutes to come away empty-handed just a week after overpowering Sydney F.C.

Now sit ninth on the ladder and with a trip to New Zealand ahead of them.

Next Opponent: Wellington Phoenix (A)

8. Brisbane Roar

Last Week's Ranking: 10

Brisbane Roar finally registered a win in the 2017/18 season with a 3-1 triumph against Melbourne City, after defender Avraam Papadopoulos netted twice to secure the victory.

The Roar are now undefeated in their last four contests, yet face their sternest test yet with an away trip to Sydney in Round 8.

Connor O'Toole and Eric Bautheac starred in the victory.

Next Opponent: Sydney F.C (A)

9. Perth Glory

Last Week's Ranking: 6

Perth Glory are another Round 7 slider after falling 2-0 at home to Melbourne Victory.

Missing key players Diego Castro and Adam Taggart, Glory struggled to execute offensively, yet were able to give 16-year-old Jacob Italiano a debut, playing the full 90 minutes.

Perth's inability to perform on the road will again be put under the microscope at Aami Park on Friday night.

Next Opponent: Melbourne City (A)

10. Wellington Phoenix

Last Week's Ranking: 7

Wellington Phoenix sit bottom of the A-League ladder and bottom of the weekly power rankings after their away trip to Western Sydney was postponed.

Without the opportunity to back up their first win of the season which came in round 6, the Phoenix are a difficult side to rank, but a home fixture against the Mariners is a golden opportunity to rise up the table.

Next Opponent: Central Coast Mariners (H)
