We should definately try and bid for Juan Mata. He's a brilliant winger and would no doubt benefit our team and the Premier League standard. We also need a creative playmaker, and although Modric is a ideal man for the role, we shouldn't broaden our options; we should also look out for Mountinho and maybe even Toni Kroos. Hamsik if we can afford him.
Hamisk would be an ideal signing tbh, I am not too keen on Toni Kroos as he seems to be the player who loves to play as a ACM in the final third while what Chelsea need is a deep-lying playmaker, someone who has the intelligence to sit back whilst having a great passing range and the creativity to open up Opposition Defences by spraying passes to the attacking midfielders/Forwards
