And Cannavaro isn't the first person to mention Pogba still has much to prove lately. A little harsh, a little reactionary. I remember thinking last season, before he did his hammy against Dortmund that he was really almost there. He'd been so consistent up to then and I wouldn't have considered him particularly immature or selfish. I don't remember any long or bad form slumps up until the beginning of this season. With the onus now on him, he seemed confused as to what he needed to start doing differently from seasons past and ended up sucking for a while. I reckon he didn't need to start doing anything much differently, just keep his head down and keep improving as he had been. He didn't need the added pressure of Marotta and Allegri publicly reiterating his new found pressure in the media. I'm sure that didn't help.
But his slump is over now, he's played with more maturity than ever without compromising his quality. Maybe he's only really dominated a few games (since his slump) but between those games he played more than solid, mature and responsible football and managed to set up several goals with moments of magic.
All players have form slumps, so it seems a bit harsh to say how far he is from being complete. He's not too far. I think a lack of goals has made him seem less effective this season than seasons prior but he's set up and assisted plenty. All he needs to do now is improve defensively but maybe he was never going to become that kind of player anyway??
