I ve also heard of his defensive coverage in those cases, but i believe that in serie A, he just cant cut it!! Just like i said before, in Spain they rather mark with speed, than physicality. Italy is not EPL, or even Germany, but they do have a load of strong midfielders and the opposition is accustomed of facing harsh defending!
But his CMs skills can be proved really helpful, actually more helpful than his DM solidarity. I also believe that his new balanced role will fit him more and he will unlock more of his potential.
But for the games Sissoko will be out

, our defensive solidarity will be compromised and i dont think that Poulsen can do much to change that... I hope that he will find his "balls", if we keep him...
