I dont think many people believe he is as good as Mbappe in terms of skills. Majority are probably just mocking your childish insistence in saying he is not Mbappe. Whats your point? Every player is different. Lautaro Martinez is not Mbappe but i want him in my team for sure.
Exactly nobody is saying he is better or worse than Mbappe. Just one guy who said Felix was much better than him, Mbappe is much better than him and he was a less creative version of Alexis Sanchez at 18. These are the same ones who say he has a lot of hype.
Intriguing isn't it?
Let him be himself and we'll see how useful he can be for Arsenal. For me, he was a good guy, for 6 million euros for a guy who just turn 18 and has already 10 G and 4 A in 1120 minutes. Good pace, good workrate, eye for goal.
