The visitors get us started...
What an atmosphere at Upton Park the crowd are certainly up for this one. Sure Sam Allardyce didn't need to get his side going.
The players are in the tunnel area and are making their way out...
Allardyce: 'We are hopeful that we can give Man United a good game this afternoon.'
Sam Allardyce's side lost 3-1 at Old Trafford just before Christmas, while the clubs met twice at Upton Park last season, with both games finishing 2-2.
However, the reigning champions will be facing a West Ham team on a three-match winning streak at home which has helped to ease the club's relegation fears.Successive away defeats by Everton and Stoke, though, have ensured West Ham are not safe yet in 12th position and six points ahead of the bottom three.
The turnaround against Olympiakos came on the back of a 3-0 home humbling by old rivals Liverpool in the Premier League and left United languishing in seventh position.United have consistently failed to follow up a positive performance and result this season, but will finally hope a corner has been turned ahead of the trip to Upton Park.
Manchester United will be hoping the UEFA Champions League win over Olympiakos does not prove to be another false dawn when David Moyes takes his team to West Ham United for Saturday Night Football.The Red Devils overturned a 2-0 first-leg deficit to beat Olympiakos 3-0 at home on Wednesday as Robin van Persie's hat-trick secured a quarter-final spot.
David Moyes: 'Rio Ferdinand has a bad back and because of this I will use a mixture of Carrick and Fellaini in central defence.'
