Defender Rio Ferdinand set a record for a British player when he signed for Manchester United for £30 million. David Beckham left United for Real Madrid for £25 million last year.
Rooney's departure is bound to cause resentment among Everton fans where it had been hoped his prodigious talent would help revive the club's fortunes.
Scores of Manchester United fans gathered outside Old Trafford today hoping for a glimpse of the player.
Andy Rowley, 24, from Shropshire, said: "It is great we are still signing world class players."
Jeff Ward, 58, from Wilmington, Kent, said: "I think he's really going to be an asset to the team, provided he keeps away from prostitutes."
