The Portuguese midfielder is set to double his current wages after another prolific season which has seen him top the Old Trafford scoring charts with 28 goals.
His agent Miguel Pinto flew into Manchester on Tuesday to step up talks with United – and the club wants the deal to be sealed before the Euros.
Fernandes said: “My priority today is to win trophies.
“Collective titles are more important than individual titles and we are working on that here.
“I think the club has improved a lot since I arrived here.
“It is in a growth phase and the players are getting more and more the mentality that you should have in a club like Manchester United, which wants to win titles and more titles.
“That's what we're here for. I feel like I'm part of that and I'm here to help the club evolve."
His current contract still has four years to run, but United want to reward him for his stellar performances.
Fernandes' adviser was keen to learn of United's summer transfer targets.
But his hopes of inserting a buy-out clause in any extension was dismissed immediately.
