Clint Dempsey struck two minutes into injury time for Tottenham to rain on Robin Van Persie's parade at White Hart Lane in a 1-1 draw.
Van Persie had put Manchester United on course for a vital win when he scored his sixth goal against Spurs, but after a sustained period of pressure, Dempsey delivered Andre Villas-Boas' men a thrilling equaliser with less than 60 seconds of the match remaining.
