Thomas Tuchel makes three changes from the side that beat Atletico Madrid in the Champions League: Ben Chilwell, N’Golo Kante and Hakim Ziyech come in for Marcos Alonso, Jorginho and Timo Werner.
Manchester United didn’t play their best XI against Real Sociedad, as they were effectively through, but there are two changes from the 3-1 win over Newcastle in their last league game: Scott McTominay, fit again, and Mason Greenwood come in for Nemanja Matic and Anthony Martial. That means
Mason Greenwood will play up front.
