Manchester United skipper Wayne Rooney expects a tough challenge against West Ham United.
Rooney is underlining the importance of taking three points against Sam Allardyce's men.
"They're always important games and obviously the most important one for us is our game against West Ham," said Rooney. "We have to try to focus on getting three points there.
"It's the end of a big week for us. We knew going into the Leicester game that the next three games - Leicester, Cambridge and West Ham - it was going to be an important week for us.
"It's a difficult place to go and win, especially this season, you can see they're playing some good football as well.
"They're aggressive, they get in your face, so it's a tough place to go, but we have to be ready for that, ready for the battle, and hopefully show our football."
