Nah, I think they were reading the Caf and seeing people didn't want him because it would hamper Martial's development.
I think he would have been fine if Bruno came along and would complement with Martial nicely. Either way, he's made a good choice for his career. He is having a monster season, but I think he has to prove himself over the next couple of season. Right now, he is still some distance away from Mbappe in my eyes when it comes to the player that's going to take over the mantle from CR7/Messi, because every defenders know Mbappe now and he's still producing at a higher level each and every season. The way Kimpembe handled Haaland in the CL showed that the big Norwegian doesn't seem to handle physical pressure very well despite his frame, he will have some growing pains. He might very well end up being the best player in the world if he adjusts and keeps developing, or a solid striker for years to come, or he could also be a flash in the pan and is having one of the best season of his career, it's just too early to make any definitive statements, no matter how eye-popping his numbers in the league and CL are right now.
