Manchester United boss David Moyes admits they cannot afford to slip up against Everton tonight.
United trail fifth-placed Everton by two points, but most attention is on a nine-point gap at the top Moyes fears could become insurmountable, if it opens up much more.
"Yes there is (a concern we cut be cut adrift)," he said.
"We've got to make sure we keep ourselves close enough to be competing. We got ourselves in a really good position after beating Arsenal at home, but then we slipped up at Cardiff. We've got to make sure there aren't any more slip-ups."
