Pellegrini, meanwhile, will ignore calls to recall Joe Hart in favour of sticking with blunder keeper Willy Caballero.
Caballero had a shocker in last week’s FA Cup thrashing at Chelsea, but has played in every round of the Capital One Cup this season and Pellegrini will keep faith with the Argentine.
He added: “I manage a team in my way of thinking, one that is the best way to do it and I don’t change it.
“It’s not an obligation to my word, it’s an obligation to think that we are doing it one way in that tournament. It’s important to try to finish until the end in the same way.”
