There is every chance of that as United have a six-point lead and four matches over the festive period - starting with tomorrow's trip to Swansea.

"We have every right to expect a challenge. I think that's what we're good at.

"And if we are top on New Year's Day, everyone else knows fine well that we're going to be in the ballpark at the end of the season."
