Mixed feelings about this.
Right now, I couldn't give two hoots about reaching the FA Cup final. In the long term it could rebuild confidence, but PL has to be paramount.
So with an upcoming game against City it could be a useful opportunity to rest weary or disillusioned legs, giving time to rebuild strength.
Nevertheless, as
@N.S.N.O. mentioned, I doubt Big Sam will be resting too many players. With extra days over other teams, he'll want to win this.
Another defeat, or worse another embarrassing performance, and Martinez's head may be in the stocks. It could also lower confidence even more.
I would much prefer City coming here after a win, rather than a fifth straight defeat. A victory will boost the squad more than a match off.
Therefore, I think the core of the starting XI needs to be playing if they're fit and able to do so. They need to dig in deep and try and win a game.
Let's not risk players needlessly, for example McCarthy if he isn't ready, but let's give the lads an opportunity to turn this round.
Another defeat will put Robert and the club in a difficult position regardless who is playing!
The only person I would drop is Barry who right now needs to stop and rebuild some form, as currently he doesn't deserve to be starting.
