Crystal Palace boss Alan Pardew is surprised by Manchester United's recent form.
Both teams go into the game on the back three defeats in a row, and United's run has surprised the Eagles manager.
"They come here with an unusual record for a Man United side. They have not scored or won in those three games," said Pardew.
"They are the biggest club in the world and it's an important game for them. We're in the same position for different reasons.
"We have got to safety and not quite produced the focus and mentality until we played Chelsea last week, which I thought was very good.
"On another day we could have got something, so if we can produce and get the process right against Man United then we can get something from this game on Saturday.
"I was really pleased with our Chelsea performance."
