Alonso has set the bar high at Bayern Leverkusen in the period he was the coach that the team's management and fans will be looking forward to seeing the team improve more. Ten Hang once did something marvelous with that Ajax young team some years ago, his credentials were in doubt when he was at the helms of affairs at Manchester United. I believe with the right players, he can actually achieve great things with Leverkusen.
If Leverkusen can still perform well for next season with Ten Hag, then the team that is mostly formed by Xabi suits Ten Hag. But if Leverkusen performs badly at the start of the season with Ten Hag, then what will definitely be obtained is criticism, where what happened to United will be repeated at Leverkusen.
Everyone certainly does not want that to happen, Ten Hag may not be suitable for United. But hopefully, he will be compatible with Leverkusen and get praise.
It is certain, Ten Hag will be heavily criticized if he fails to meet expectations, we know that competing for trophies with Bayern Munchen in the Bundesliga is very difficult, and repeating the success that Xabi Alonso once achieved is even more difficult, but at least Ten Hag must ensure that Leverkusen does not experience a serious setback to the point of having difficulty competing at the top of the standings.
Ten Hag must work hard so that his adaptation period takes place quickly, and that way Leverkusen can perform consistently from the start of the season. Ten Hag career will fade if his performance at Leverkusen is also not good, his reputation as a manager will be at stake. Meanwhile, Ten Hag must find a suitable replacement for Florian Wirtz and Jeremie Frimpong.
