Xabi Alonso + Leverkusen = 
Ten Hag + Leverkusen =
I'm sure I'm not the only one doubting Ten Hag. We can realistically look at Ten Hag's time with Man United with some professional players and it ended badly. Meanwhile, Leverkusen don't have top players like Man United who can put pressure on Ten Hag. I find it strange why Leverkusen's management chose Ten Hag as Alonso's replacement. There are many coaches who are more modern than Ten Hag.

Ten Hag has his way of training and having players with bad behaviours in the team will affect the whole of them.
For Bayer Leverkusen, they are playing in the Bundesliga, a less competitive league comparing to English Premier League with less stress and more disciplined players.
I expect him to have more fluid experience and good results at least for the next season unless they will not be a real move to consolidate the squad and good replacement for the players who will leave in this summer transfer window.
