Southampton stunned Chelsea with a 3-1 win at Stamford Bridge to inflict further misery on Jose Mourinho and the Premier League champions tonight.

Willian fired the hosts into a 1-0 lead with an excellent free kick, but Steven Davis's fine volley just before half time ensured parity at the break.

Goals from Sadio Mane and Graziano Pelle then completed the scoring for the Saints in an error-laden second half from the Blues.

Here, Sports Mole sorts the heroes from the villains on a dramatic night in West London.

Goal

Asmir Begovic: It could and would have been far worse for Chelsea if not for Begovic, who pulled off a host of excellent saves to thwart the visitors. Unfortunately, he was the Blues' best player, which tells its own story. (7/10)

Defence

Branislav Ivanovic: Hugely lucky to not have a penalty awarded against him moments after Chelsea opened the scoring. Looked okay at times, but it will not keep the critics away as the Serbian continues to struggle at right-back. (4/10)

John Terry: Was turned by Mane far too easily for the second goal, but atoned for it somewhat by blocking Tadic's goal-bound effort to make it 4-1. Still, it was not the way that the skipper would have liked to mark his return after a brief exile. (5/10)

Gary Cahill: Looked uncharacteristically sloppy as Mane tormented him regularly in the second half. His mistake also led to Southampton's crucial second goal. (3/10)

Cesar Azpilicueta: Inexplicably lost possession in a dangerous area for a mistake that directly led to Southampton's third goal and arguably killer goal. (4/10)

Midfield

Ramires: Like Ivanovic, the Brazilian could, and should, have conceded a first-half penalty when he fouled Mane. Replaced at half time for Matic, whom he replaced in the first XI. (4/10)

Cesc Fabregas: The game passed him by once again as he struggled for an influence at either end of the field. Could, and should, have been subbed. (4/10)

Oscar: Buzzed around plenty as usual but had very little end product and spurned a number of hopeful opportunities with wayward finishing. (4/10)

Willian: Opened the scoring with a stunning free kick but he was simply nowhere to be seen after that and found himself subbed off for Pedro. (6/10)

Eden Hazard: Started brilliantly and won the free kick that led to the opener, but slowly and surely became less influential as time ran on. He continues to look like a shadow of the man that won double Player of the Year gongs last term. (5/10)

Attack

Radamel Falcao: Lacked the same presence as Diego Costa - who has now served his three-match ban - and never really had the pace to trouble Southampton. Booked for diving in the second half. (4/10)

Substitutes

Nemanja Matic: Subbed on at the break, and off again on 72 minutes when Chelsea went 3-1 down, but had done little wrong. (5/10)

Pedro: Saw very little of the ball as Bertrand marshalled him well during his cameo. (3/10)

Loic Remy: Had the guts of 18 minutes to make an impact but he never got going. (3/10)

Goal

Maarten Stekelenburg: Could do little about Willian's free kick, such was the quality of the strike, and had barely anything to do after the break by way of saves. He was given the benefit of the doubt by Bobby Madley when Falcao went to ground in the box. (6/10)

Defence

Cedric Soares: Excellent showing at right-back as he coped well with Hazard and Azpilicueta to a lesser extent. Barely put a foot wrong. (7/10)

Jose Fonte: Shackled Falcao brilliantly in both halves as the Portuguese emerged with a huge deal of credit after a dodgy start to the season. (7/10)

Virgil van Dijk: Should have easily won a first-half penalty, but put the disappointment to one side and helped Fonte with Falcao. (6/10)

Ryan Bertrand: Impressed on his return to Stamford Bridge. Should have scored in the first half after Begovic denied him, but he was excellent in defence and the full-back can be proud of his Chelsea reunion. (7/10)

Midfield

Victor Wanyama: Brilliant midfield display from the combative Kenyan as he proved an excellent sentry in front of the visiting defence, blasting everything that came within his radius. (7/10)

Oriol Romeu: Endured an unconvincing return to Stamford Bridge, being hauled off at half time after being booked for conceding the foul which led to Chelsea's opener. One to forget for the Spaniard. (4/10)

Steven Davis: Atoned for a glaring first-half miss with a fine equaliser just before the break. Passed the ball well throughout and proved an excellent outlet for the Saints in both halves. (7/10)

Dusan Tadic: One of Southampton's quieter players on the night as he struggled for an influence overall and from set pieces, with his deliveries often slightly erratic. Should have added a fourth but Terry threw himself in the way. (5/10)

Sadio Mane: Superb. Just a superb performance from Mane, who was central to everything that Southampton did in the final third. Scored the second, set up the third and was a general nuisance to Chelsea's defence all night. Outstanding. (9/10)

Attack

Graziano Pelle: Scored one and set up two, but was far less involved than his Senegalese counterpart. Still, played a huge role in the victory. (8/10)

Substitutes

James Ward-Prowse: Subbed on at the break to great effect as he gave Southampton's midfield a turbo charge. (7/10)

Jay Rodriguez: Replaced Tadic after the third goal but saw very little of the ball. (4/10)
