Manchester United skipper Wayne Rooney says they won't underestimate Newcastle United tomorrow.

Talk of Alan Pardew being sacked subsided last month after he took Newcastle on their own six-match winning run, but the Magpies have struggled recently, losing their last three games.

"They've had their highs and lows - they started badly and there were a few shouts for Alan Pardew to lose his job. I'm happy he wasn't sacked and I think they went on to win five or six games in a row," Rooney said.

"They haven't picked up as many points as they would have liked to in the last few games, but it's always a tough game against Newcastle."
