Kylian Mbappe is one of the best football players in the world right now. I think you can easily say that. Even if there are objections on this issue, I think we will not see much objection. Although his career was full at PSG, remember him in the last world cup. He's a beast in international matches, too. So the team that owns it will be very lucky.
No one doubt that Mbappe is one of the most valuable players in the world. That's why he has an expensive price, not every club has the ability to sign him. Sure, he doesn't only won the title in PSG, he also won the title with France national team.
