I can't see how Monaco can keep Mbappé, or rather, why Mbappé would elect to stay, if they sell Lemar, off the back of selling Bernardo Silva, Germain, Dirar, Bakayoko, Mendy, and most likely Fabinho too. Their season has disaster written all over it and surely the kid is smart enough to know the only way is down after that one off achievement last season? There's being loyal and then there's wasting a year of your career.
For that reason, I'm not sure we'll get Lemar. I think Monaco know his departure is the straw that will break the camel's back. He goes and I think they all go.
