But how did United’s players fare? Our man Danny Hall offers his player ratings from the game.
5. Enda Stevens 7
Didn't give Janmaat a moment's peace down the left and came inside to hammer one shot over Foster's goal. Looks full of confidence as he prepares to depart on international duty Photo: Simon Bellis
6. John Lundstram 7
An energetic display from the midfielder from the right channel, getting on the ball as often as he could and looking to break through the lines Photo: Tim Goode
7. Oliver Norwood 7.5
Recycled the ball intelligently early on to keep United in possession but almost let in Watford with an underhit pass to Lundstram. Otherwise so, so calm in possession and threw his body in the way when needed too Photo: Simon Bellis
8. Callum Robinson 6
Caught a volley well from McBurnie's knockdown but fired it straight at Foster, who gathered after flicking it into his face and battled hard as ever but was dealt with relatively comfortably by the home defence Photo: Simon Bellis
