Bayer Leverkusen are competitive club and they're always trying their best to accomplish winning points. Xabi Alonso was competent, he won major trophies with the club but something was missing and that's consistency, we see them as a one season wonder. The ex Manchester United boss, Erik Ten Hag was one of the potential manager to manage Manchester United but guess what happen, he couldn't apprehend a good pattern for his players.
Erik Ten Hag to Bayer Leverkusen and Xabi Alonso to Real Madrid, this is the desirable changes we've been waiting for, seeing these managers swapping positions to manage elite teams, a good start for both of them. Xabi Alonso stand a better chance go explore in Real Madrid than Erik Ten Hag in Bayer Leverkusen. Secondly, Erik Ten Hag should not be judge based on his past records in Old Trafford, he's in Germany to open a new chapter with Leverkusen.
Oh, I was waiting for which club Ten Hag will coach next. Well, Bayer is a very good team and Ten Hag is lucky that he will coach this team after Alonso, because Bayer is now in a very good team spirit, and the team is in much better shape than Manchester United was. Actually, with Ten Hag, Manchester United is not so bad (although far from ideal), and after his departure, everything became even worse. I doubt that Bayer will be able to compete with Bayern, but Ten Hag will have the Champions League.
