If the club wanted to sell Sane, or if indeed he wanted to leave, he'd have been long gone by now. Much is made of and read into pep's attitude towards sane and sane's body language. Again, if pep wanted him gone, woulda happened right at the start of the summer, like the swift exits pep and tixi previously arranged for the likes of ronaldinho, eto'o, ibra, hart, nolito etc.
Whenever the lad spoke publicly he was always professional and showed no frustration at not playing, saying he was fighting for his place. And on the pitch he does, i have no issue with his performances OR his 'attitude'. he had one and a half bad game (against stubborn teams) and two shrugs of the shoulders, and folk write his whole season off. Pep has also always said the club want him here.
So despite all the noise from Bayern, its a case of he agrees a new contract this summer, or he doesnt, either way, he starts the season as a City player. Maybe he agrees a new contact by next summer, maybe he doesnt. He still plays the whole of next season with us.
