"Probably this time a year ago he wasn't playing this regularly for Swansea". He gets kicked, gets back up, goes again.
"I think it's our best performance of the season", said Solskjaer.
The Norwegian labelled the 3-1 win as "exhilarating and entertaining" as Andreas Pereira, Marcus Rashford and a Davy Propper own goal handed his team a second comfortable win in the space of four days after the 3-0 victory over Partizan Belgrade on Thursday.
The contest was put to bed shortly after the halftime break, as Ashley Young picked out Rashford in the penalty area for an easy tap in.
Brighton, meanwhile, offered nothing going forward in open play for most but only looked threatening on a couple set-pieces as De Gea was largely untested in the opening 45 minutes.
Scott McTominay has been an integral member of the Man United midfield so far this campaign.
It was a cagey first half, with the home side creating a few half chances and the Canaries looking to hit on the counter in response. Their five-game form has showed their struggles.
Brighton would go on to clinch all three points with relative ease, and will now look to continue their good form on Sunday.

"Of course the Bournemouth game was disappointing but we've had loads of answers to what we're trying to do and if we don't get confidence from this, I don't know what to tell them". Scott McTominay and Harry Maguire sustained knocks against the Serbian giants, and might miss the match. Both are now potential doubts for the weekend. Victor Lindelof remains sidelined due to a back problem, but will be a game-time call.
