Talk of a classic straw man and non sequitur fallacy.
First. The Debate isn't 'is Pogba world class". That's a straw man. The debate is can Pogba perform at optimum level in a tactically structured team. Juventus and France are proof he can, end of story.
Second. Giroud is irrelevant to the debate. He has never had issues in a tactical structure thus there is no reason to bring him up. So that us a non sequitur. Furthermore You also show up the inane level of distaste you have for Pogba when you try to dare equate the level of Giroud as a player to Pogba. Both in general and in that French world cup winning team. A team that was structured around Pogba and fully harnessed his best qualities that led them to glory.
