Manchester United manager Ole Gunnar Solskjaer speaking to Match of the Day: "We should have scored many more goals.
"It was an excellent performance from the lads, when you see them going forward it is a joy to watch.
"Anthony Martial did not get a goal but he was outstanding. Brandon Williams was excellent too - he has had some good games already and he seems he wants to be out there and enjoy himself.
"The table does not really matter at the moment, we need to keep improving and keep winning games and see where it takes us."
Brighton manager Graham Potter, also to Match of the Day: "They deserved to win the game, if you make any mistake they can turn defence into attack so quickly.
"The players gave their best, but sometimes you have to accept you are playing against a better team. We had a decent period in the league and now we need to get ready for another tough match.
"They key moment for us was when we went 2-1 down despite not being much in the game, if we could have kept that score for longer it could have made a difference but United responded scoring the third goal so early in transition."
