Ot's not a bad scheme but on the other hand it is difficult to do and might even sound quite impossible to do.
There are many factors that make this not a reality, as we know that currently Haaland and Mbappe are being used as substitute players for rivalry issues, especially the Ballon d'Or because our two goats Messi and Ronaldo are already in the final phase of their careers so they is being looked at as the next candidate, apart from that the high price and total salary expenditure will be a consideration for these two players not being able to be together in one club unless the club is immune from regulations but in the end there will be no such thing as expecting Mbappe and Haaland in one club which is equally clear this will not be able to happen I think.
They are 2 young stars who have potential and I think they will only be suitable as rivals, not as friends at the same club.
Bear, this is not an easy thing to do and indeed uniting these two players indirectly means you have to be prepared for high salary burdens and the level of selfishness of each because looking at what is happening now it seems that uniting Haaland with Mbappe is the same as uniting Cristiano and Messi, which is definitely very difficult to happen and I can't expect much from this.
Indeed, when these two players are united, it will look like a perfect club for today's times, but money and regulations also have to be thought about because after all, with the strict FFP situation, no one will be able to get away with trying to unite two players who have potential, regardless of how rich the club is. but still FFP will act unless perhaps it is free like SPL but of course that will not be a consideration for either.
