Coman has actually developed a lot under Jupp, showing signs he is not that headless chicken I also thought he was a year or two ago. He has taking massive steps in the right direction.
When you say it was a borderline criminal offence to let Costa go you make it sound like Costa is the only winger out there, and Bayern is a small club who cant attract any players

Honestly I dont see it as a mistake. Might it turn into one with time? I cant put that away totally, but for now I dont see it as a mistake at all.
Another reason Bayern decided to skip him (according to media) was his greedy behavior wanting a lot more in salary and the club didnt see him worth getting a pay rise.

Well reaching 3 straight SF´s under Pep is not exactly what I would call bad - but - if you look at the bigger picture I offcourse agree we dissapointed.
But thats because there are so massive expectations to Bayern Munich as a club, and it certainly was even more while Pep was here. This year we have gone more under the radar which is nice for an exchange.
About all the Costa talk, Im happy for you guys if he is doing well in Juventus but he wasnt the solution here.
