West Ham v Man Utd preview

West Ham manager Sam Allardyce will still be without defender Joey O'Brien and forward Marco Borriello when reigning Barclays Premier League champions Manchester United visit Upton Park on Saturday.

O'Brien has not featured since a 0-0 draw at Chelsea in January, due to a dislocated shoulder, and on-loan AC Milan striker Borriello remains sidelined with a calf injury.

Midfielder Joe Cole came off the bench in last weekend's defeat at Stoke for only his second league appearance.

Meanwhile, striker Robin van Persie will miss Manchester United's game at West Ham on Saturday because of a knee injury.

United will assess winger Antonio Valencia after he sustained a gruesome black eye against Olympiakos in midweek.

Defenders Jonny Evans (calf) and Chris Smalling (hamstring) are doubtful, but Nemanja Vidic is definitely out through suspension.
