All signs are pointing to Sane signing for Bayern, Bayern's latest denial made it more so (because they don't want to get into trouble and complicate things with City). In my opinion Sane is a bit overrated and is nowhere worth 137m which is rumored to be the price tag City put on him.
By all means City, milk as much money as possible from Bayern, they are loaded.
I think he's an exceptional talent and has all the tools to be an elite player nevertheless he has a lot of attitude issues it seems. This is a guy who tattoo himself from a game that saw his side get KO'ed his lack of work rate is the reason he hasn't been getting into City squad he'll be like James and Ozil type lot of talent but a luxury player who can hardly put in a shift, no way would City let him go if they believed in him but he hasn't changed in 3 years there.
