Manchester United manager Jose Mourinho has ripped into his side for making a number of "incredible mistakes" in their 3-2 loss at Brighton & Hove Albion.
"We were punished by the mistakes we made," Mourinho told BBC Sport. "For me that's the story of the game. We made incredible mistakes in some crucial moments. Mistakes that killed us.
"Especially that third goal - we expected to come at 2-1 with positivity - then the third goal killed us off in the second half. Our second goal came too late.
"The week leading up was good and I expected the team collectively to be better. There are basic mistakes that makes almost an impossible mission to win the match."
United have conceded four goals in their opening two games of the season, a tally that took them nine games to reach last term.
