Jose Mourinho: Manchester United made big mistakes against Brighton

Speaking after the game, Mourinho told the press: "We made big mistakes and were punished.

"The accumulation of those mistakes, and the fact that they were punished by goals, gave confidence to Brighton and took it away from us."

Brighton's striker Glenn Murray said their 3-1 home win over United last season gave them confidence that could spring another surprise.

"It was all about the balls being played in to me, I got quality support," said the striker.

Mourinho had started with Anthony Martial but the winger, who is reported to be unsettled at the club, made little impact even when Jesse Lingard and Marcus Rashford were brought on at halftime in an attempt to give United more of a threat up front.
