PSG supporters think he sucks?! I don't think so tbh...
And about the Juve supporters.. most of the negativity comes from this forum because a lot of people here seem to love negativity. By no means is he a bad player. Is he what we need? That's certainly up for debate but what u sometimes read here is just utter nonsense. Everybody wants the bling bling stars and big names but seem to forget that we are not Real Madrid. Plus no one can tell u anybody that would've helped us that was available (for an at least somewhat reasonable price). N'Zonzi for 40mio definitely wouldn't have been better business. Anyway, I think Matuidi will add a lot to our midfield. Just see for urself
