While that change to the team is enforced, Frank Lampard freshens the side up further after the sapping 90 minutes in Spain three days ago by bringing back Fikayo Tomori and Emerson Palmieri in defence, Mason Mount in midfield and Pedro comes in for Willian in attack.

Jorginho is captain with Cesar Azpilicueta rested on the bench. Andreas Christensen and N'Golo Kante are the other players moved from the team to the subs. Fit-again Callum Hudson-Odoi is also on the bench.

Among the West Ham changes is a debut for 33-year-old David Martin in goal with Roberto dropped. The visitors bring Fabian Balbuena into their central defence for suspended Issa Diop who was previously ever-present.
