Deal maker Keith Harris says no amount of cash will accelerate Manchester City's chances of winning championships.

Harris masterminded Thaksin Shinawatra's initial takeover of Manchester City and said current owners the Abu Dhabi royal family must accept that money cannot guarantee success.

"Money isn't everything, as Real Madrid showed when they spent all that money on top players a few years ago," said Harris.

"I suspect Manchester City could spend £1billion and still be some years away from winning the championship.

"Sven-Goran Eriksson was asked by Thaksin how far City were from a championship-winning team and he replied 'four and a half miles'."
