I think he was best option out of the little options you had tbh. Nagelsman I still don't feel is ready, at least for Bayern. I think he would do good job at Dortmund though, and I get a feeling he will go there in place for Peter. I haven't heard about Favre going to Bayern tbh, maybe it's just me though. I don't think disaster will happen simply because of small profile, nearly all of Barcelona's manager are small profile, and are amazing team no matter the manager. I find it funny Frankfurt and Kovac were both denying it, and couple of days later he becomes manager lol.
Starting from next season, Niko Kovač will be Bayern's manager on 3 year contract!
Our first requirement was for coach to speak German, so after Tuchel's deal broke down we were stuck with either Kovač or Favre (Nice). Kovač was the choice because he has Bayern DNA, he spent some time in the club and knows everything about Bayern and our philosophy.
Kovač started as a youth coach at RB Salzburg doing great job, but soon left for Croatia for his basically first real job at the 2014 World Cup, we failed in key game and that sent us home. After that he was employed by relatively unknown club to non-Bundesliga-supporters, Eintracht Frankfurt where he has done awesome job and is currently in 5th place, 2 points behind Bayer with direct qualification for CL.
As Jupp said, Kovač did great work with basically unknown players with different profile and nationalities, knows how to do with young players, knows hard work is the key and sets up defense very well.
Although main opinion between Bundesliga fans is that Kovač is defensive coach, he really isn't. Truth is he wouldn't be able to keep Eintracht this high without playing defensively. I'm sure he will start with better and more attacking football as soon as he comes to Bayern. Kinda like Conte or Valverde - coach who can setup team defensively well but also make a team which doesn't struggle in attack. Eintracht had some great offensive displays, especially in second half of the season.
Mia San Mia.
