Graham Potter has gone with a back four for both of his first games at Chelsea, so expect the same here. Conor Gallagher could start here after scoring the winner against his former club Crystal Palace, as well as Christian Pulisic who set up the winner. N'golo Kante, Edouard Mendy will miss the game. Jorginho could miss out after picking up an injury last weekend. Chelsea need a win for their group stage chances, so expect a strong side here. Stefano Pioli has a very injury-hit side on their trip to Stamford Bridge. He will be without Mike Miagnan, Theo Hernandez, Divock Origi, Alessandro Florenzi and veteran forward Zlatan Ibrahimovic. Three more players, Davide Calabria, Alexis Saelemaekers and Simon Kjaer came off injured on the weekend, and could miss the fixture. Ante Rebic came off the bench to score against Empoli, and should start with the amount of injuries AC Milan have.
Chelsea and AC Milan both picked up wins in their respective league games on the weekend, but Chelsea will be favourites coming into the game against Milan. Graham Potter picked up his first win as Chelsea manager away at Crystal Palace and will be looking to getting their first win of the Champions League campaign when they take on last years Serie A winners. As for Stefano Pioli, his side are carrying lots of injuries, and will be without eight players for the trip to Chelsea. They still managed a win in Serie A on the weekend, but Davide Calabria, Alexis Saelemaekers and Simon Kjaer all came off through injury. Chelsea know a win can get them level with AC Milan before they travel to the San Siro next week, which will give them hope in their efforts to qualify from the group stage. 2:1
