Nope. Always a risk when you are swapping superstars. See Coutinho...Pure speculation on my part, but would anyone be willing to lose Salah next summer, if that was part of what it took to be able to sign Mbappe?
We've got a humble, hardworking and effective front 3 with great comraderie. I would rather keep them together as long as possible.
Breaking the wage structure and an aspect of the team that is our strength, seems too much for Mbappe, even if he is a great player especially with PSG looking to extend him for €50m a year !!!
At that salary, it isn't a choice between Mbappe and Salah... it is choosing between Mbappe and much of the squad.
