Nah. Not even close. Tevez affected the game overall in far more ways. And also was far more consistent, especially in CL.
Dybala's goalscoring has matched Tevez for the most part, but Tevez created a lot more for his teammates, and had a much higher workrate.
I don't really care much about the workrate, it's something I doubt Dybala will ever possess, but I do want him to make some progress in terms of working together with and interplay with his teammates. For whatever reason, outside Mandzukic in that first season, he's never seemed to mesh well with other attackers. Morata, Higuain, Ronaldo, Costa, etc. I find his positioning and offball movement can be really poor at times and same deal with picking out teammates for a pass, although this wasn't entirely his fault in the Higuain era, as Higgy was terrible moving off-ball while here, and was slow as heck in terms of first step. With Ronaldo, I'd like to see Dybala take the creative side of his game up a notch this year. He'll be unstoppable if he does that.
