Fernandes, 31, is on the verge of breaking the Premier League’s single season assist record with 19, just one behind holders Thierry Henry and Kevin De Bruyne.
The attacking midfielder was heavily linked with a move to Saudi Arabia last summer but ultimately remained at Old Trafford.
Speaking to Gary Neville on Sky Sports, Fernandes admitted that succeeding at Man United means more than any potential move.
"It's not a question of loyalty. I could have gone two years ago, I could have gone three years ago, I could have gone last season, but I really like to be here,” he said.
"I think that being successful at this club is something that I can never get at another club. The joy and everything I get, the day I get what I want from this club, I don't think I will get that from any other club in the world.
"I know how much the fans want this, I know how passionate they are. I know how much they are waiting for the club to come back again. I'm on the same ship as them. I want this ship; instead of being steady, I want it to go forward and to navigate as much as we can.
"Yeah, I won the Carabao Cup and the FA Cup (but) what this club wants, what these fans want and what I want, myself and the team, we haven't got that yet. Until my contract expires, I'm going to try."
