United implode against feisty basement side Watford

Not even the returning Paul Pogba, on as a second-half substitute, could save his misfiring team, who again struggled to impose themselves against one of the league's lesser lights.

The key moment in the match came in the 50th minute when De Gea somehow allowed a tame, spinning effort from Ismaila Sarr to creep through his hands and in at the near post.

Watford doubled their lead four minutes later when Troy Deeney fired home from the penalty spot after the otherwise impressive Aaron Wan-Bissaka brought down Sarr with a misjudged sliding tackle.

Nigel Pearson coaxed a battling performance from Watford in his first home game in charge and they deservedly won just their second league match of the season to give themselves hope of survival.

But for United it was another story of failing to make the most of their domination of possession.
