Haha are you saying that Mbappe is nearing retirement because of his age? If I may ask you, at what age is it standard in your world to retire? Mbappe is 24 now!

I doubt that he is dealing with retirement already or that Manchester City thinks age is a problem in the case of Mbappe.
But they may know more than everybody else. Perhaps their did reach out and see whether a transfer could become possible or not and if Mbappe's people said that it is either Real Madrid or some absurd offer from Saudi Arabia, then there might be no point for them to prepare an official offer.
It’s laughable thinking Mbappe is nearing retirement age. He’s still young with lots more to give. Retirement is probably the last thing on his mind. Manchester City may not have plans for him to have him in their squad or they did reach out and could not afford to have him. Definitely nothing to do with his age.
I think it has always been Real Madrid on his mind but now, another mouth watering offer from the Saudis is on the table. Would the offer take his mind off a future deal playing for Real Madrid?
