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.
