I don´t know who you are writing half of that to, because I haven´t mentioned his position, let alone written him off as a CDM.
His profile would be......attacking mid like Iniesta, that was what was intended for him but he has shown no sign of being that type of player since joining the first team squad. His last season was as occasional fill-in for Busquets. But all of that is a bit besides the point, because despite willing him on in every game to make his mark, he hasn´t really done that in any position. Simple easy passes which I don´t think anybody who watched him could describe as "fantastic" despite the accuracy...no dribbling, certainly not enough to bother even mention his dribbling skills, let alone say he is a good dribbler.
He may have all the skills to be a much more impressive footballer, but I am not sure if he will show that at Barça, and he certainly hasn´t up until now. Players there nowadays simply don´t get the time and patience which Xavi and Inesta received in their first few years.
