Imo he was last year the second best defender in the ligue 1 after silva and was really great.He radiates a sense of calm and his really strong. Also his heading abilities are good also on one on one he is great. But he is not a ball playing defender like stones.. more a destructor. Also he was a little bit injury prone last year. Im not quite sure if hes good enough for cfc as a full starter but he available for 20 m euros, while garay would cost us at least like 30-35 m euros. He would be surely a great back at least. I knew him since he played in germanY when he used to play for bremen. I think he came directly from africa and was used as Left Back where he played sooo shit..because it wasnt his position. But the silly bremen coach never let him play as cb where his strenght are.. i can remember when he was bood so hard from the bremen fans... I never thought that he could make it to a cl club like monaco, but he imprived a lot in toulouse in a calm surrounding.
