• 

  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

• 

  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

  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

  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.
