It is funny that we undervalue our players so much. I don't mean commercially, I mean their quality. Jesus and Raz are top players and are very young indeed.
I accept that Mbappe is the real deal, the absolute top young star in world football, but you don't build greatness by sacrificing the strength of your squad to gain one jewel. Selling a star for a star sure, but it would be an older player for me, or one who we are less happy with.
