United have had a poor campaign by their own standards this term, already losing seven games and sitting 14 points behind leaders Arsenal with just 16 games remaining.
"What I liked most about this club is the character. If another club was in this position, it would be very difficult for them to come back and take first in the league," PA quotes Mata as saying.
"This club can do it. This club is used to fighting to the end. This is the real image I have of Manchester United; always trying to win every title and always coming back from difficult moments."
