I've spent the last few days looking at Porto matches he's played in recently and I'm fairly convinced by him. I remember him at Barca and have seen him in the CL but I wanted to really dig down on him while there's no City game on.If he plays as well as he talks, we're on to a real winner with this one!
Also not to insult Opta, but there was an article by the Opta Analyst saying that he's no Rodri regen. This is the huge difference between comparing stats and watching his games. He didn't have similar stat distribution to Rodri because he played in a totally different system, but watching him, when he was playing deeper he looked exactly like Rodri.
I think Pep wants to train him as this. He needs to learn the dark arts better, but he's much closer in how he moves the ball to Rodri than Gundo or Kova.
