AC Milan v Chelsea player ratings: Tomori 4, Giroud 4; Mount 9, Aubameyang 8

Graham Potter's side seal 2-0 Champions League win at the San Siro on Tuesday

AC MILAN RATINGS: Ciprian Tatarusanu 7: Sent wrong way by early Jorginho penalty, then left exposed for Aubameyang goal. Good save from low Mount strike just before half-time. Reuters

Pierre Kalulu 7: Important block on Sterling shot minutes after Chelsea had taken the lead and vital interception on Kovacic ball that almost picked out run of Mount in first-half injury time. Like in London last week, was Milan’s best defender. Reuters

Matteo Gabbia 5: Fine work in opening 10 minutes to cut out ball over top of defence with Aubameyang lurking. Booked for brainless shove on Mount later in half and lucky not become second player to see red for foul on James later in half. AFP

Fikayo Tomori 4: Gave away penalty and sent-off for pulling on Mount’s shoulder when Chelsea man was through in 17th minute. Nightmare early end to night for former Chelsea defender that all but ended Milan hopes of a win. AFP

Theo Hernandez 6: France defender missed last week’s reverse fixture and certainly likes to push forward - and not exactly in rush to get back ahead of Chelsea winning penalty - when Milan are in possession but his partnership with Leao down left never really kicked into gear. AFP

Ismael Bennacer 5: Fine defending early on to steal ball off Sterling’s toes with Chelsea attacker threatening to break through on goal but, like at Stamford Bridge last week, Algerian lost the midfield battle. Getty

Sandro Tonali 6: Sent over some dangerous dead balls early on and had low cross booted clear by Kepa in rare Milan attack just after half-time. Booked late in game for obvious push. EPA

Rade Krunic 6: Bosnian started in defensive role before moving into midfield following reshuffle after sending off. Booked for kicking ball away as Milan started to lose their heads in first half. AFP

Brahim Diaz 6: Former Manchester City attacker scored against Juve at weekend and it was his whipped in ball that Giroud should have scored in first half. Sacrificed after team went two goals down. Reuters

Rafael Leao 6: Milan’s key threat barely had a touch in first half but showed his quality when he surged past two Chelsea player to provide chance for Dest after break. Disappointing night again for Portuguese attacker. AFP

Olivier Giroud 4: Missed glorious chance to bring Milan level but headed Diaz cross wide of target when unmarked in box. Headed another chance well over from near penalty spot later in first half. Reuters

SUBS: Sergino Dest (On for Diaz 37’) 7: Forced into immediate action with sliding tackle on Chilwell who was charging down left. Blasted wild shot wide of target after being set-up by Leao. Good interception with Aubameyang poised to score. Getty

Ante Rebic (On for Giroud 62’) 6: Brought on try and spark Milan into an unlikely comeback but came up against a well organised Chelsea defence. One nice ball to set-up opportunity for Origi. AFP

Tommaso Pobega (On for Bennacer 62’) 5: Booked with minutes of coming on for foul on Loftus-Cheek. Getty

Divock Origi (On for Leao 80’) N/A. Had shot saved in injury-time which was Milan’s first on target. Reuters Fode Ballo (On for Hernandez 80’) N/A. Another Milan player who picked up a booking - one of six.

CHELSEA RATINGS: Kepa Arrizabalaga 7: No real save to make until having to stick boot on Tonali cross just after break and Milan registered their first shot on target in injury time which Kepa saved comfortably. Another surprisingly quiet evening for the Spanish goalkeeper. AFP

Trevoh Chalobah 8: Was prepared for big test against Leao and came through it with flying colours, albeit helped by Milan’s attacking threat being reined in by red card. Nice ball through to set-up Gallagher chance and shot another opportunity wide himself in second half. Getty

Thiago Silva 9: Brazilian, making 100th Champions League appearance, showed all of his quality and experience to block and clear Milan chance at start of second half. Did not put foot wrong. AFP

Kalidou Koulibaly 9: Former Napoli defender was immense on his return to Italy. A powerful presence at the back who helped keep Milan’s dangerous attackers quiet. EPA

Reece James 9: Hailed last week by Leao as one of the best players he had faced and it was James’ clever ball through that led to Mount winning penalty and Timori’s red card. Went down in worrying fashion after landing awkwardly, tried to play but then had to limp off. Big worry for Chelsea and England. AFP

Mateo Kovacic 8: Produced key pass in move that led to Aubameyang scoring and was magnificent from start to finish. Don’t recall the Croatian wasting a ball all night. AFP

Jorginho 8: Italian was captain on night after being left out at Stamford Bridge last week and made no mistake from spot to open scoring at San Siro, despite laser being pointed at face from crowd. PA

Ben Chilwell 8: Fine game defensively and offensively from left wingback. Once thumping low cross in second half was crying out for an attacker to finish but missed everyone. PA

Mason Mount 9: His run behind Timori ended with Milan defender pulling on his shoulder before shooting and the Milan defender sent-off. Clever ball through for Aubameyang goal, then had shot turned round for corner by keeper just before break. Taken off half-time with team in total control. AFP

Pierre-Emerick Aubameyang 8: Scored with his first shot on goal with cool, side-footed finish in 34th minute. Should have made it 3-0 early in second half when Kovacic miss-hit landed at his feet but shot straight at keeper when clear on goal. Reuters

Raheem Sterling 8: Tremendous tracking back in 10th minute to help break down Milan counter. Booked for nasty looking lunge on Kunic in first half. Looked like he was going to score Chelsea second but was beaten to ball by Aubameyang. EPA

Chelsea coasted to a 2-0 Champions League win over AC Milan at the San Siro on Tuesday, aided by an early red card shown to former Blues defender Fikayo Tomori.

After winning 3-0 against the reigning Serie A champions at Stamford Bridge last week, Chelsea were expecting a far tougher evening over in Italy.

But Milan's plans were thrown out of the window after 17 minutes when Tomori gave away a penalty and was sent-off for pulling on Mason Mount's shoulder as the Chelsea player surged through on goal. Italian midfielder Jorginho confidently finished from the spot.

It was 2-0 in the 34th minute when a fine interchange of passes between Mateo Kovacic and Mount ended with Pierre-Emerick Aubameyang side-footing home.

Chelsea suffered a blow in the second half when in-form England wingback Reece James was forced to limp out of the action after jarring his knee.

With a busy schedule up ahead for the Blues and the World Cup only six weeks away, it will be a worrying wait for managers Graham Potter and Gareth Southgate until they hear what the damage is.

The win leaves Chelsea top of Group E with seven points from four matches, with Red Bull Salzburg on six points and both Milan and Dinamo Zagreb on four.
