There's no doubt KDB is better than Pogba, he's easily most efficient player when it comes to through pass, set pieces and crosses where he excelled excellently at, the system played to his strength, we see the same thing every game, he spammed cross in the same spot and has many movements he knew could pass to. On the other hands, Pogba doesn't have his own system where he can apply to his game every game and imposed himself against others, that's why many of his chances were ridiculously that come out from nothing.
