Juan Mata insists he can handle the "pressure" over the club record fee Manchester United paid for him.
United have paid Chelsea a massive £37.1 million for the Spain midfielder.
Asked about the pressure that comes with his price tag, Mata said: "I like the pressure, I think it's good for a footballer to try to improve.
"People are expecting big things from me and I am looking forward to it."
Mata, who will wear the number eight shirt, said he was attracted by the character of United and their reputation for never giving up, even claiming they were not out of the Barclays Premier League title race.
"It's a new challenge for me," he said. "This one was a massive challenge for me.
"What I like the most about this club is the character. I think if another club were in this position in the league, I think it would be very difficult to come back and take first position, but this club can do it.
"This is the real image I have from Man United, always fighting to win titles, always coming back from difficult moments.
"The team is really good, the squad is really good. This season they have had some unlucky moments they didn't deserve. Hopefully from now until the end of the season we will win as many games as we can."
