Sane said before the tournament, he doesn't want anything to do with any of this until it's over. Most players will feel the same.
Yeah, because it would be seen as unprofessional behavior if he wouldn't say so. Of course he already knows if he wants to stay at Schalke or leave the club. That's what you got agents for. It's there job to agree a deal with the new club. If a deal is agreed, it's between the clubs to negotiate a fee. For none of these steps the player is needed, indeed he doesn't have to think about it for a second. All he needs to do is to tell his agent which club he wants to join and how much he wants to earn. All the player has to do is to pass the medical afterwards.
