Blackburn Rovers striker Roque Santa Cruz is in line for a £2.5 million bonus if he is sold in Janaury.
The People says the Paraguay striker, wanted by Manchester City and Aston Villa, has a 'fixed price clause' in his contract.
But Santa Cruz, 27, has an extra reason to celebrate if he goes for £18million because Rovers agreed he will be due a massive one-off payment should that figure be reached.
