I also made mention of his performance during the last World Cup compared to the performance he had in had in Euro and in his club before leaving for Realmadrid . Though , I won't be too quick to judge his performance that much but for me I think he's not currently on form compared to the Mbappe I used to know because I'm a very Big Fan of him.(Mbappe).
As for Lewandowski , I think he's doing a good job eventhough it's not enough but comparing is age to that of Mbappe and he's having alot of goal though he lost some chances at the very beginning of the season that was somehow obvious (I could remembered I complained about that in one of my comments:)) but I think he has improved in his recent games . However, I hope Mbappe (Adapt)

like others are saying
Every football lover have the back of their mind, their favorite players. Many stick to Cristiano Ronaldo and Leo Messi but they're out of the current picture, we're now watching the replacement of these undisputed GOATs in European football, however the comparison is quite different and from sectional phases. Kylian Mbappe have always been in his prime, playing his best for Paris Saint-Germain and he's yet to fetch the deserves titles with the club. He moves to Real Madrid to win major titles and he will win because he deserve everything coming his path.
