Not quite there yet, in my opinion. Zidane was bossing in a much better Serie-A, and he also set La Liga, the Champions League and the international stage on fire. Let's cool it just a lil' bit...
Pogba is doing exceptionally well, and I'm not ruling out that he may someday surpass Zizou, but to say that he's "better than Zidane" at this point in time is way premature.
