Our Premier League Team of the Week is back again, in a week where many thought Liverpool showed their title credentials, Arsenal swept Chelsea aside and Crystal Palace came from 2-0 down to beat Sunderland.

Two Arsenal players in the defence

Petr Cech (Arsenal): A year on from his move to the Emirates Stadium from Chelsea, and Cech has proved to be the upgrade in goalkeeping quality that Arsenal need. He was excellent again on Saturday as the Gunners won 3-0 against his old side, and with Thibaut Courtois going through a difficult phase, you must wonder if Arsenal's London rivals may be regretting that particular sale.

Hector Bellerin (Arsenal): The Spanish full-back has been exceptional of late, and his rapid rise over the past year has been hugely impressive. Against Chelsea, his defensive contribution was excellent as he kept Eden Hazard quiet down the left hand side, and got back brilliantly in the second half after a mix-up at the back to stop Pedro who was in on goal. Bellerin's s attacking presence was superb too, as he supplied the assist for Arsenal's second goal, scored by Theo Walcott in what was a quality all-round display.

Virgil van Dijk (Southampton): The towering Dutch centre-half was a key player for Southampton as they triumphed at the London Stadium. Van Dijk was a huge presence when it came to dealing with the Hammers' aerial threat, winning several important headers and putting in just as many impressive tackles to help them seal all three points and keep a clean sheet. He was particularly unphased during the 15-minute spell where West Ham bombarded the Saints.

Steve Cook (Bournemouth): It was a 1-0 win for Bournemouth at home to Everton, and the man who is often an unsung hero, Steve Cook, was everywhere. He made a number of vital tackles, headers and interceptions at the Cherries became the first team this season to beat Ronald Koeman's men.

Ryan Bertrand (Southampton): After recording his first Premier League win, Claude Puel's Southampton continued in resolute fashion, beating West Ham 3-0. It was their fullbacks who led the Saints to keeping another clean sheet, with Ryan Bertrand playing a key part. The England left-back was a constant menace in offence and assisted Charlie Austin's opener and was also aerially and physically dominant, as the Hammers were frustrated once more.

Liverpool light up the midfield

Ander Herrera (Manchester United): Entrusted with playing as the deep midfielder behind Paul Pogba, Herrera made the most of his chance with a starting performance in United's big win over the champions. Breaking up a number of Leicester City attacks with a strong defensive effort, the Spaniard's biggest influence came with the ball at his feet where he played a big role in United controlling the possession. Herrera showed good poise when under pressure, finding his teammates on most occasions, showcasing his excellent short-passing ability which was crucial in wearing down the opposition at Old Trafford.

Adam Lallana (Liverpool): Where has this form come from? Having been heralded as the 'nearly man' for much of his career on L4, Lallana has suddenly become a huge contributor to Liverpool's side, having scored three and assisted three this season, having been moved to a deeper role. He continued his form against Hull City, opening the scoring with a neat finish into the corner, whilst impressive off-the-ball work made him deserving of two simple assists picked up later in the game. 

Philippe Coutinho (Liverpool): Another Liverpool player thrown into the mix, Philippe Coutinho was simply excellent against the Tigers. A quick dribble and pass set up Lallana for the opener, before it was his goalbound shot that was handled on the line, reducing Hull to 10 men. Not afraid of getting on the scoresheet himself, he bent a beauty in from 25 yards to restore order just after the visitors had pulled a goal back.

Son and Sanchez in an in-form front three

Heung-Min Son (Tottenham Hotspur): Another man in terrific form, Son virtually won Spurs three points away at Middlesbrough single-handedly. Playing from the left off Vincent Janssen, he used the striker's hold up play to open the scoring, before doubling his side's lead with an extraordinary curler from 25 yards. They needed both the goals too, as Ben Gibson would go on to pull one back in the second half. 

Jermain Defoe (Sunderland): The Sunderland striker rekindled his form from previous campaigns against Crystal Palace this weekend, following a barren spell in front of goal. The England striker netted twice - two trademark, well-taken finishes - and his goals could still help him stake a late claim for an England recall. Defoe's brace put his side into a seemingly comfortable 2-0 lead, although his team-mates let their talisman down, conceding three late goals to lose 3-2.

Alexis Sanchez (Arsenal): Sanchez, put into a striking role by Arsene Wenger, was fantastic against the Blues as Lucas Perez and Olivier Giroud watched on from the substitutes bench. Opening the scoring with a delicate dink over Courtois after he ushered Gary Cahill into a mistake, the Chilean was at the heart of everything good Arsenal did in their commanding victory.
