Sunderland captain John O'Shea insists team spirit remains rock solid.
The Black Cats are recovering from a humiliating FA Cup defeat at Bradford City.
"We have to draw a line under what happened now, but that'll be easy to do," said O'Shea.
"It's an important stage of the season, and we're not going to allow an FA Cup defeat to get in the way of what we know we need to do in the league.
"Yes, it's disappointing, and we know how much it means to everyone to have a good cup run.
"I'm sure people were thinking it was a great chance for us, and it was.
"But it's gone now and there's nothing we can do about it, so we have to forget it very quickly and focus in on the job in hand.
"We need to stick together and move on."
