To compare this guy with R9, Pele or Messi is such a huge disrespect to those legends... I saw R9 and Messi play on a weekly basis, they are absolute geniuses of this sport, one of a kind, we'll probably never see something similar in our lifetime. Nobody controls the ball like these guys, technically they are the absolute best in their respective positions. R9 was also a physical beast, and Messi too actually given his inferior physique.
Regarding Mbappe, Xavi said it best: the kid relies much more on his physical attributes, he's good technically but nothing special really. His performance against MU was a total joke technique and skills wise. Here in France he's overrated as fuck right now. Constantly compared to GOATs of this sport. And I used to love the kid. But the press and media do him no favor with such comparisons because now it looks like he embraced the exaggerated hype.
Mbappe was a lovely and humble kid back in his Monaco days. Since he's at PSG, he's clearly becoming arrogant. Winning the WC accelerated the process. Just look at his behaviour on the pitch these days, especially vs MU. He thinks he's the boss, gives orders to his senior teammates, all this while he's having a horrible performance. Reminds of worst CR7 version honestly.
The kid is still talented, the kid is still the most promising player of his generation, but he'll never be half a Messi or half a R9. People need to realize this and stop BS comparisons, especially french media. They have to do it for Mbappe's good first, such hype is toxic for a 20yo kid.
Mbappe is a Thierry Henry level talent, which is a great praise since Henry was one of the best in his era.
