alberto bueno may go to you from vallidolid about 1.2 million should get him and he can play in the premier league
craig dawson from west brom you could loan or loan to buy.
jordi gomez may go to you from wigan on loan or loan to buy.
tony sliva the african goalkeeper (cant remember where from) is a good free transfer aswell.
