James Trafford said he does not care if he has a "point to prove" after joining Leeds from Manchester City in a move that makes him the most expensive British goalkeeper in history.
The England player, who moved in a deal reportedly worth up to £45 million ($61 million), said he was looking forward to a fresh challenge after a frustrating season at the Etihad.
The former City academy player, 23, returned to the club from Burnley last year but City then signed Italy goalkeeper Gianluigi Donnarumma, who became first choice.
Trafford made just 17 appearances in all competitions but played a major role in City's League Cup and FA Cup triumphs.
"I don't really care if I have a point to prove," he told LUTV. "I know my own abilities. I go out and try as hard as I can and have as much fun as I can.
"Everything that comes with it is what it is. I am really excited and just really happy that it is finally done. I can get onto preparing for the new season and can focus on getting in with everyone next week.
"It is one amazing club, full of energy and passion –- the club and the fans."
Trafford, who has signed a five-year deal with Daniel Farke's men, was a member of England's squad at the recent World Cup but was not given any on-field minutes by manager Thomas Tuchel.
He is Leeds' third permanent addition of the summer transfer window, after the arrivals of midfielder Harry Wilson and defender Tarik Muharemovic.
Trafford's fee surpasses the figure of £30 million Everton paid Sunderland for Jordan Pickford in 2017.
He paid a heartfelt tribute to City on Instagram.
"To everyone at Man City, it was my dream to play for the first team from when I moved away from home at 12, and it makes me so proud to have achieved that last season, whilst also winning 2 trophies in the process.
"The fans singing my name was something I dreamt of when I went to the Etihad growing up through the academy. I wish nothing but the best for the club for the future."
Leeds launch their Premier League campaign away to Nottingham Forest on August 22.
