Hmm, this is a long shot, but have you thought about Modric? I know normally you wont get him for a penny under £40 million, but in a man utd save, i first admired him, and got a positive response from him, so i declared an interest. i offered £35 million for him, and Tottenham tried to negotiate for £45 million, i withdrew and Modric pubically criticised Harry Redknapp for not letting him discuss a contract with me. I then bid £24 million for him, and it was accepted. Bit over your £20 million budget, but Modric is really worth it. Might be long shot, but worth a try? And i dont know much about Lucas Moura, but i really doubt you'll get him for under £20 million.
