Ozil is a great player but I would question the mental side of the game as he doesn't seem to be tough enough. But he is an excellent player and if it were to be a straight swap with Cesc then it would be good for both clubs but only if we were to sign another midfield player like Koke or Torres, Ozil on his own would not work for us.
But a Masch, Busi, Iniesta, Rafina, Xavi, Koke, Ozil midfield would have extraordinary depth and talent which is what we need, but I don't know how realistic that would be.
As for the other rumours, Bravo would be an excellent choice for a No. 2, I think with him in goal instead of Pinto we could have won La Liga and maybe the cup not sure about the Champions League but I think we could have got past Atletico with a good keeper.
Mathieu is a good solid CB who would add strength and depth to our defense and though he would not be first choice by any means would certainly add to the squad. His buyout is £20m which is far too much so if we can get him for around £10m then that would be a good signing.
Koke had a wonderful season but there is always the risk that he would not fit into our system, but unless a player comes from La Masia then that will always be there. He is young, Spanish, knows La Liga and the Barca players from the national team and has proven he can play at the top level. I think he is as sure a thing as we are going to get, but £60m is far too much so Zubi better have improved his negotiation skills.
Kun would be perfect if not for his injury problems, but I would still take him in a heartbeat. I would prefer Reus though but Kun would still be an excellent purchase.
Don't know anything about Cuadrado.
Last year everyone wanted Marquinhos, now not so much. But he is still the same player who has all the attributes needed to be a top class defender so if we can get a good price then we should go for it.
