There's no striker who're in the same level to Mbappe, even Haaland and Osimhen are behind Mbappe. Both Haaland and Osimhen without support from teammates will not able to score, but Mbappe without teammates is still able to score, he can do alone.
If Mbappe leave PSG, PSG won't be same and it's impossible for them to win Champions League.
Honestly how a striker who plays in an uncompetitive league can be better than a striker who plays in the most competitive league at the moment?
I don't think we can compare Mbappe and Haaland at different levels when they play in different leagues at the moment, I think the experience of playing in some of the tight competitions that Haaland has gone through has made him a sharp striker, We can see how Haaland performed when he played at Dortmund as well as now when he plays in the Premier League, while Mbappe he only played in Ligue 1, and I think if later Osimhen replaces Mbappe at PSG then Osimhen will be very better than Mbappe because indeed PSG does not have opponents who can indeed make it difficult for them in Ligue 1, PSG's dominance in Ligue 1 would make it easier for Mbappe to score as many goals as possible and obviously make a name for himself in Ligue 1, but would Mbappe be able to do that if he were to play in the Premier League?
Of course not...!!
The game of football is a collective game and no one best player can be the best without the support of one team, so when you say Mbappe doesn't need his teammates when it comes to scoring goals of course it looks like a joke to me
. If indeed mbappe can score goals without needing help from other players, of course it is better for PSG at this time will only play mbappe alone because it can be guaranteed to win with mbappe's ability to score goals as happened in the shaolin soccer movie.
