"I'm happy here. The club is massive, the support we have is massive. I've been settled down in the city since year one," Mata, who has scored once in 13 appearances this season, told ESPN.
"I'm 29 and hopefully I can play football for some more years. It would be great to play until I'm 40 like Ryan Giggs. But that's still a bit far, still 11 years.
"You never know what can happen in football and in life. But my feeling now is that I'm happy here and I wouldn't have any problem continuing here for more time."
United, who are second in the Premier League, eight points behind Manchester City, host Brighton and Hove Albion on Saturday.
