I could even image an attendance or success bonus on that. Schalke made a meal out of that for five years after selling us Neuer.
What I liked about him as a young player breaking through that he could really play shit for parts of the match but that he always could have his moments later in the match. Other players you knew that it is a loss with them when they make mistakes as they think about that for the whole rest of the match. But - it could be that when he plays bad or unlucky he might not survive long in matches with Pep. Have seen that with Müller who had some of his best matches when he looked terrible in the first half but was match winner in the second - not really with Pep.
As I told before - I am not really sold on Sane. It is not so much because of his quality - I think he is a great winger but needs the matchplay being adapted to him - but because of the transfer situation - and yes, the mentality issue. I do not think he is in a higher talent class than about same age Coman or Gnabry. Gnabry now really started to deliver and has made the step from talent to star. But he is a much more direct player like e.g. Robben was. Coman lacks the end product but is great in holding and carrying the ball - if you have the other three offensives delivering numbers in the way they do this season that is a special treat, too, in a ball playing system. But with Heynckes Coman had a good end product - he just has been injured too often in the last two years. With Davies and his speed and quality going forward as a fullback on the left side an inverted, direct right footed player would be the optimum. Sane is not that so that he probably would have to be starting on the right - and change his match.
Actually Bayern is not home. Sane is home in the west of Germany. And I do not know if it is not easier for him to live in England than in Germany. What might feel more home to him are some of the players he knows for ages like Goretzka, Kimmich and Gnabry. His father might like that his old coach Gerland is the assistant again - and Flick who he knows well is the coach.
Actually there are paralells.
Kroos went because Bayern did not want to pay him the money that he wanted at that time. He was a talent then with sparks what he could become, but drove you really crazy with his laziness and lack of defensive awareness - not in a different situation than now Sane. Wanted to already earn as much as the top earners. Müller and Kroos were offered similar raised wages in autumn of 2012 - Müller extended, Kroos did not. He and his agent after that played games - e.g. when his agent brought Moyes (then United coach) to the stands in a Bayern match - but Bayern told that they only would extend to the fair conditions they offered to him. They sold him a year before he would have been a free agent.
