So what's this about Suarez buying out his contract to get his freedom

[The Tony]

Shrewd play....would instantly become the most sought fryer player in the world....can u imagine our wages to him in that case? Would be like £500 a week

[Rich]

out of pocket? He would go to Madrid if he could just choose anyone.

How much would it cost to buy out his contract and is there any legal issue with doing it?
