Oh I would love that (esp if Haaland goes to Real), but realistically speaking, as much as I am pining hardcore for Mbappe to sign for us, the chances of that happening are quite slim
The chances for any players are usually slim, since plenty of big clubs are after him anyway.
Halaand could opt to City and Mpabbe will then be between RM & EPL, or he could just change his mind and renew with PSG. We could just fail to afford any even if they want to move here.
I am just pointing, that currently an elite athlete top priority is to create his own brand, and that won't happen with old RM model of galactico. The CR7 going to Madrid to challenge Messi is probably the best.
Media has already started to create the rivalry between both, as football need that.
I would say we have better chance on Mpabbe, than RM getting both Mpabbe and Halaand
