Real will get him I think. Morata will more than likely leave when an enormous bid comes in, and Mbappe will sign.
Ronaldo
Bale
Mbappe
Benzema
Asensio
Isco
Those 6 will be Reals attacking players going into next season. Hand on heart I can't see him opting for Arsenal and likewise I can't see Arsene agreeing to part with over £100m in a single transfers. Especially considering Ox, Ramsey, Alexis and Ozil will be asking for more money as they all try to get new deals. It all seems very far fetched and just all in all, very unArsenal.
