Joe Coe set up both of West Ham’s goals
Robin van Persie scored in stoppage time as Manchester United remained in the FA Cup by the skin of their teeth and denied West Ham a famous win.
Tom Cleverley gave the visitors the lead when he sidefooted in before James Collins headed the equaliser and his first goal for the club, reports the BBC.
Collins gave the Hammers the lead with another header after the break.
With seconds remaining, Van Persie latched on to Ryan Giggs's through-ball to earn the visitors a replay.
