Mourinho said on the United website that 42-year-old Faria, who he has worked with since 2001, was ideally situated now to become a manager in his own right.
On Saturday, Ray's wife Jackie Wilkins, will present the trophy from the Royal Box to the winners at full-time.
Faria is one of the names who have been linked with filling the large vacuum being left by Arsene Wenger at Arsenal.
The Red Devils improved from sixth to second in the league this season and have the FA Cup final against Chelsea to look forward too.
But there was still a moment to remember late on as Carrick's 464th United appearance came to a close, receiving a standing ovation as he was replaced by Paul Pogba on a day that belonged to one of the club's most distinguished servants.
"I'm starting to think the Mourinho factor is losing its impact and if he's not getting results in an entertainment industry then he's under pressure".
While legendary midfielder Michael Carrick is set to join Mourinho's coaching staff after hanging up his boots, he will not move directly into an assistant manager's role as the United manager has admitted that he simply won't have a traditional assistant for the coming campaign.
"Manchester City have had the most outstanding of seasons and Jose Mourinho measures himself by title wins, not finishing second".
"The question at Manchester United is which players do you keep and which don't you keep", he added.
Jose Mourinho has picked out that player and it's, surprise-surprise, Anthony Martial. It's not just game to game but half to half. People who know how to win and don't drop their standards week in, week out.
Chelsea has had a torturous season so far after failing to qualify for the Champions League and losing 3-0 to former boss Rafael Benitez' Newcastle United. They have lost against all three promoted teams, that's nine points.
Do you think United will need to spend big in the off-season in order to catch City?
