John O'Shea says Manchester United's squad will be pressed to the limit over the Christmas period.
"It is never easy at this time of year when the games are coming thick and fast and I am sure the manager will be rotating," said O'Shea.
"Everyone who gets their chance will be up for it. That should work in our favour.
"The main thing is when we get on the pitch we keep picking up the three points.
"We are only a point behind Arsenal, so we have a lot to look forward to."
