I mean they're definitely getting him. They wanted him when he was at Schalke but City beat em to it. If anything, Sane's time in England is done. He's won everything there is to win in England. Might as well do the same in Bayern and get back into the Bundes national team.
City just trained him for Bayern to be honest. They were always gonna come back for him. Kinda like Barca with Fabregas. And as a German, when Bayern comes calling you gotta answer that call.
This might as well be considered a done deal. Right now it's just the formalities and agreeing on the final transfer fee
