Manchester United chief executive David Gill has admiited that the club’s attempt to sign Carlos Tevez is becoming “over-complicated”.

The deal is in limbo after the Premier League said it must be done between United and West Ham but not Kia Joorabchian, who claims he owns the 23-year-old’s economic rights.

“It’s become over-complicated,” said Gill. “Effectively, we are trying to work with four parties.

“We’re dealing with the player, West Ham, the company who own his economic rights and the Premier League.”

Tevez is reportedly preparing to fly into Manchester for a medical which, but last week West Ham dismissed claims that Tevez was set to complete his move to United.
