Thomas Tuchel has made five changes to his team to face Zenit St Petersburg for tonight's opening Champions League fixture, including the return of Mason Mount.
Following the 3-0 win over Aston Villa at the weekend, Tuchel has made two changes to his defence, with Cesar Azpilicueta coming back in as captain and Andreas Christensen also returning to the side. Antonio Rudiger continues as our third centre-back in front of Edouard Mendy.
After being introduced from the bench at half-time on Saturday, Jorginho is back in the starting line-up tonight to partner Mateo Kovacic in midfield, flanked by Marcos Alonso and Reece James, who was suspended for our Premier League fixture following his red card against Liverpool.
Zenit make three changes from the side that beat Akhmat Grozny 3-1 in their last game to go top of the table in Russia, as South American trio Wilmar Barrios, Claudinho and Malcom all return after being rested at the weekend.
