West Ham United boss David Moyes is looking forward to the challenge of taking on his old club.
The Hammers are facing Manchester United at home on Sunday in the Premier League.
As Moyes' side look to pick up a few more points to all but guarantee safety from relegation, the Scotsman is hoping that result can come at the expense of a club he used to manage.
Moyes told reporters: You learn a lot when you watch all the good teams play.
Manchester United are a really good team with terrific players. The manager [Erik ten Hag] has done a brilliant job with them this year, so overall they've got a good side.
We had to play one of the best teams a few weeks ago in Arsenal [and got a result]. Now we've got to play another of the best teams in the Premier League in Manchester United, so we'll have to play very well.
I'm looking forward to it, we need to play at our best. If we play at our best we'll give them a really good game and if we get the crowd behind us the way they did against Arsenal, it'll give us a great opportunity of getting a result."
