Wow, that sounds dangerous but on the other hand he shows that the club decides. I really hope that Mickytarian stays at least.
It's not really dangerous. If we sell two of those players, we'll get €40-60m, add another €15-20m which we can easily spend. And we don't really need to sign that many players. If we sign both Dembele and Götze, midfield would be stacked and we'd still have €20-30m to spend. Depending on whether Tuchel really sees Merino as a CB, we might not even need a Hummels replacement with Sokratis, Subotic (if he stays), Ginter, Bender and Merino. Obviously not the quality we had with Hummels but that's not happening anyway, we'd need to hope for Ginter or Merino to make that step up. So, €20-30m for a CB, a LB backup and maybe a new Weigl should be plenty enough.
The risk that one of the players who's forced to stay will play shit is small as well. Gündogan is gone, the least important out of the three players and City will pay enough money. Considering how long it took Micky to get to a good level, I severely doubt he would play shit for a year before moving clubs. And Hummels, yeah, he might as well leave the country if he played shit for BVB in his last year lol
