WEMBLEY: Chelsea will play Arsenal in the FA Cup final after a comprehensive 3-1 win over Manchester United at Wembley on another difficult day for David De Gea.

If the Spanish goalkeeper was possibly at some fault for Olivier Giroud’s first half opener, he was most certainly culpable for a shocking error to somehow allow Mason Mount’s second half strike to beat him when.

Harry Maguire’s own goal sealed a fully deserved victory for Chelsea, with Bruno Fernandes’ late penalty a mere consolation.

It was only a first defeat in 19 for Ole Gunnar Solskjaer, but the manner of the performance will be a worry as will yet another error by De Gea – who must be under threat from Dean Henderson for next season’s starting spot.

Chelsea are into a ninth FA Cup final this century as Frank Lampard seeks to end a promising first season as Stamford Bridge with a trophy.
