Non-casuals know Kante's easily been France's best player. Even most of the French roster agrees but Mbappe getting all the hype for one great game against a terrible Argentinian team.
Well not really. There actually has not been any French best player this tournament as Lloris, Varane, Kanté, Pogba have all been very consistent in the first 6 games. But
Kylian has had the highest peaks (Argentina and Belgium).
Without Lloris decisive saves against Uruguay or Belgium, we wouldn't be there. Without Varane rock solid appearances since the start we would have concede a couple more of goals/chances, without Pogba dictacting the pace and surging through the midfield, we would not have. And without Kylian's pace and creativity, we would have put less fear in the opponents (who would be scared of our counter with Giroud-Grizou upfront alone ?). You may hate the hype but it's totally legit as King Kylian is nuclear dissuasion. With him, you can basically prevent any team to play a high line because it's inevitable that he will get behind or brutalize the back line or the opposite left side with dribbles.
Argentina was proof enough, Belgium too as he killed it there too (he could have had 2 or 3 assists). The thing you may overlook is even though he can play on the wings, Mbappé is a 9 and the only reason, Giroud starts instead of him is because of seniority and it's Deschamps' strategy. Mbappé is R9 reincarnated (instincts, pace, dribbling, finishing), there's many similarities between him right now and PSV R9, look it up. Oh and get on the bandwagon now, it's leaving
