Debast will be the best IMO. He impresses me the most. Technically sound, his passing is so creative for a CB, he also has a nice shot that he needs to use more often. Scored a screamer against Lille in the CL. His problem is his over confidence. His errors are not because of his limitations but because he's too cocky and sometimes he overplays it. He's very young and I think that with playing time and experience he will become one of the top CBs in Europe.
Only my personal opinion of course but I'd put Inácio at second. Quality, ball playing CB, great passing, he has been playing at high level from such young age and he has been an integral part of this successful period of Sporting and is now cementing his place in our NT. It's a matter of time until he moves.
I put Diomande at third because although he has the best physical tools of all our CBs, he's a bit raw sometimes and error prone. Of course he's also very young and will evolve with experience and the right environment. I put him at third but if he fixes some of the concentration lapses, positioning errors and keeps evolving, he probably has the potencial to become the best of the 3.
Quaresma is a decent and serviceable CB who can play many positions. He's a good squad player. Dunno if he is top European club material but he has been good for Sporting and played a vital role in our two league wins. Everybody says that he's a great guy to be around, with good personality and positive influence in the dressing room. I think clubs need a player like him. Not a surefire starter but dependable when called upon and with great character.
