Anthony Martial came off the bench to score a late winner for Manchester United against Tottenham.
The French forward, introduced in place of Marcus Rashford midway through the second half, settled a cagey encounter nine minutes from time when he latched on to Romelu Lukaku's headed flick-on and fired past Hugo Lloris.
Lukaku had hit the post for United just minutes earlier, shortly after Dele Alli had missed an excellent chance to give Spurs the lead.
The hard-fought win sees second-placed United move three points ahead of Spurs, who remain third, and to within two points of Premier League leaders Manchester City ahead of their trip to West Brom on Saturday afternoon.
