In defence, Malo Gusto replaces Reece James while Tosin Adarabioyo is fit to return. He comes in for Josh Acheampong. Trevoh Chalobah and Marc Cucurella are the other defenders.

Enzo Fernandez and Moises Caicedo continue in midfield. The Ecuadorian makes his 100th appearance for the Blues, who will be wearing our new third shirt tonight.

Maresca’s third change is in attack as Liam Delap starts, with Jamie Gittens making way. Joao Pedro is expected to be deployed in a deeper position.

Cole Palmer was due to start but was replaced in the starting XI shortly before kick-off by Estevao Willian, who makes his full debut.
