Yaya started declining last season. He hasn't been very good these past two seasons. Yaya at City always looked like a immobile stuffed turkey to me, more so these days.
Pogba has the technique to score great screamers, but he does need to hone his shooting skills and score more from outside the box. He has the ability but needs to polish it. For his size and height, he also should be a big aerial threat. Those are the technical things he needs to work on. Mentally, he still needs to be more consistent. Pogba's best month was Jan 2015. If he can play like that every month...aycaramba. And he doesn't make nearly as many mistakes as he used to before (esp in his own half), but decision-making still needs a bit of polishing too. That shortcoming isn't pronounced at all now though.
A smaller version of this should be a new smiley
