1. Sydney F.C

Last Week's Ranking: 1

The Sky Blues' A-League onslaught rolled into Adelaide and escaped with all three points after toppling an in-form Adelaide United side 1-0.

The win lifted them five points above second placed Newcastle on the table, a gap that is unlikely to be overcome as the season rolls on.

Josh Brillante played a superb game in midfield and striker Bobo netted the winning goal just prior of half-time to keep Sydney atop of the rankings.

Next Opponent: Western Sydney Wanderers (A)

2. Newcastle Jets

Last Week's Ranking: 2

The Jets suffered their second loss in three contests, both to fellow top three teams, following a disappointing 2-1 defeat at the hands of Melbourne City.

Newcastle had a golden opportunity to put space between the top two sides and the rest of the A-League after going up 1-0 thanks to Andrew Nabbout's fifth goal of the season, but their inability to cap off the performance on the defensive end cost them dearly.

Face a crucial away trip to Perth in round 10.

3. Melbourne City

Last Week's Ranking: 5

Melbourne City have risen back up the power rankings with a performance few saw coming, beating the Jets on the road to get their derailing campaign back on track.

After a tumultuous month and conceding early in Newcastle, City fought stoically through goals from Ross McCormack and Manny Muscat to deliver one of the most influential results of the 2017/18 A-League season to date.

Dean Bouzanis starred in goals for City, pulling off crucial early saves to keep the contest alive.

Next Opponent: Central Coast Mariners (H) 

4. Central Coast Mariners

Last Week's Ranking: 6

The Mariners' excellent month of football continued with their first back-to-back victory of the campaign, overcoming the Glory 1-0 in a frustrating affair for most of the evening.

Daniel De Silva's rise to prominence has been one of the biggest story-lines out of Central Coast this season and the midfield wonder boy did not disappoint against Perth, setting up the match winner after winning possession in the back half.

Right-back Jake McGing played an outstanding role in the win, which places them fourth on the A-League table.

5. Adelaide United

Last Week's Ranking: 3

Facing the sternest test in A-League football, a fixture against the dominant Sydney F.C, United fell short in their efforts to win their third consecutive game after falling 1-0 at home.

The Reds weren't embarrassed by any stretch of the imagination however, outplaying Sydney for large chunks of the night, however, they could only manage to have one shot on target against a sturdy defensive unit.

Huge game this Friday night against old rivals Melbourne Victory.

6. Melbourne Victory

Last Week's Ranking: 8

Kevin Muscat's men pulled off a much-needed Houdini trick to escape with the chocolates in New Zealand, catapulting them into sixth place on both the A-League table and the weekly power rankings.

Melbourne displayed plenty of resolve to maintain composure after going down 2-0 by the main break despite dominating for most of the first half, with second half goals to Besart Berisha and James Troisi securing the three points against the lowly Phoenix.

Off-season signings Rhys Williams and Leroy George starred yet again for the Victory, ultimately proving the difference in the entertaining contest.

Next Opponent: Adelaide United (H)

7. Brisbane Roar

Last Week's Ranking: 9

The Roar's A-League resurgence rolled on in Western Sydney with their second win in three games, outplaying the favoured Wanderers on their home deck to the tune of 2-0.

Maccarone and Franjic scored on either side of the break to deliver the victory, whilst Eric Bautheac and Daniel Bowles starred in the upset.

Have a perfect opportunity to make it three wins in four hosting Wellington in round 10.

Next Opponent: Wellington Phoenix (H)

8. Perth Glory

Last Week's Ranking: 4

After overcoming their road woes with a drought-breaking away win against Melbourne City, Perth fell back into old habits with an uninspiring loss in Central Coast.

Potentially hard done by in the rankings but given the tightness of the mid-table a sole win or loss has a monumental impact on each club's positioning, with just four points separating fourth and ninth on the A-League table.

Defender Alex Grant was exceptional in the loss and kept the Mariners at bay on numerous occasions.

Next Opponent: Newcastle Jets (H)

9. Western Sydney Wanderers 

Last Week's Ranking: 7

A round 9 slider, the Wanderers went win-less for their seventh straight game as a result of a 2-0 home loss to Brisbane in a dour outing for the struggling club.

Josep Gombau was left with few positives during the loss, with his side failing to pose a real threat to the Roar defence, while injuries to Oriol Riera and Jaushua Sotirio added salt to the wounds.

Hosting a huge Sydney derby in round 10.

Next Opponent: Sydney F.C (H)

10. Wellington Phoenix

Last Week's Ranking: 10

Wellington remain in last place in the power rankings for the third consecutive week after giving up a 2-0 lead at home to fall to the Victory.

Andrija Kaluderovic headed home two goals in the space of three minutes to put his side in a promising position, drawing level with Roy O'Donovan at the top of the Golden Boot.

An away fixture against Brisbane Roar presents a chance to register their first points since round 7.
