I agree House, watched him in the champions league and he really stood out for Shakhtar Donetsk, he would be a great player to get on a free.
Sotiris Ninis could be worth a gamble. He is creative, and is young. Would be really helpful on the right wing as well as in the middle.
I think we would be silly not to try and get Andres Guardado for free, he is a great player.
