Compared to Erik Ten Hag, I think for some reason I prefer Niko Kovac because I think he has quite good experience in the Bundesliga and maybe he is suitable to coach a big club like Dortmund, previously he was the coach of Bayern Munich and won the Bundesliga title and the DFB Cup in the 2018-19 season and also became the coach of Eintracht Frankfurt winning the DFB Cup title and the Runner-up position in the Bundesliga so if he coaches Dortmund, it is possible that he can improve the performance of this club which is currently slumping.
I also agree more with your opinion on this one because from the series of experiences and results that Niko Kovac has obtained which are specifically focused on the Bundesliga, it is very good compared to Erik Ten Hag who was fired by Manchester United because he could not change the team for the better. So I hope Dortmund can have other options besides Erik Ten Hag unless there is no choice at all for the others and only Erik Ten Hag is left at this time as a coach who does not have a job at another team after being fired by Manchester United.
