Pogba's off ball movement will only get better with age, especially since he's working with players like Marchisio and Vidal (also tevez until he went to boca), also his off ball work-rate has only been bad for the past 2 months, like i said injury, plus he was playing in an unfamiliar position in the 4-3-1-2 as a left sided midfielder when he usually plays in the hole or in the center. Like in the game against Madrid people gave him shit for not marking Carvajal AND Bale whilst also being a counter-attacking threat, he did very well considering the circumstances.
he's 22 right now and you'd have an easy time picking whether you wanted yaya toure or him on your team
I think Juventus' team is perfectly balanced in the midfield right now for a 4-3-1-2, they have a great holding midfielder with box-to-box abilities in Khedira, two fantastic engines and technically well rounded players in Vidal and Marchisio who can play as shuttlers on the sides with Pogba being able to play anywhere in the midfield but particularly in an attacking role. They have great rotation players in Perreyra and Sturaro.
