Manchester City boss Mark Hughes will do all he can to prise Roque Santa Cruz away from Blackburn Rovers this week.

The Mail on Sunday says Hughes will have to bid in excess of £20m to sign the Paraguay international.

Hughes has been persistent in his pursuit of the Paraguay striker, whom he took to Ewood Park from Bayern Munich for £3.5m in July 2007. But new Blackburn boss Sam Allardyce is equally determined to keep the player. He could be fighting a losing battle, though.
