"Over the 90 minutes they were the better team and fully deserved to win," the Fulham boss said after the game.
"We can't even complain about the margin of victory.
"What impressed me was that there is not a player who is not comfortable on the ball and not composed.
"All I can do is congratulate Manchester United on an outstanding performance.
"We lost to a better team, but we stuck at it.
"We have to accept we've got some big games ahead of us and hope we'll be able to learn lessons from today and play better in the games ahead."
