My main concern about him is he doesn't have any real experience. The Brazilian league is a joke, to put it lightly. I seem to remember Marlon being the next Thiago Silva and even Jamdav of all people thought he was quality and compared him to Abidal... but look at him now. I want him to be a success as he's young and appears to be solid in the air, but all the highlights I see of him all have something to do with his on the ball skill, which are completely irrelevant. In the back of my mind I feel like I've seen this exact scenario play out before and as of now I'm not expecting him to live up to the potential.
