Ndombele is not going to be starting this game.
In that case, given he's realistically not going to start both Tues and Thurs next week, either (i) he sits out two games in a row (Sun and Tues) or (ii) he doesnt play on Thurs in the EL.
My guess is that he's likely to play on Thurs and therefore I'd play him on Sun. The Chelsea game will be 110% mph so not sure its suited to him
