Manchester United boss Sir Alex Ferguson has revealed why he allowed Carlos Tevez to move to Manchester City. United have been criticised for failing to seize the option of buying Tevez for £25million in 2009 after he had spent two seasons on loan at the club.
Tevez joined rivals Manchester City instead and has become a cult hero with the Blues.
But Fergie told the Sunday Mirror: "Tevez told us he was only going to play for four more years.
"If we had signed him on a five-year contract knowing that he was going to quit in four, there would have been no re-sale value for us.
"I'm not sure Inter would pay £45m, especially after he's said he wants to go back to Argentina to see his kids. I can see him staying at City."
