Goals from Harry Kane and Lucas Moura sealed a memorable result for Mauricio Pochettino’s side away from home.
Manchester United started the game with more urgency and the hosts should have gone into the lead. However, the likes of Lukaku spurned easy chances and they were made to pay in the second half.
Two goals in quick succession from Kane and Moura put the visitors in a comfortable position. The Brazilian winger added his second of the night six minutes from time.
Jose Mourinho was already under a lot of pressure after the Brighton defeat and it will be interesting to see how United bounce back from this one.
