That's because Ajax cannot be compared to Manchester United. If the problem really is player recruitment, then it makes sense because Ten Hag intends to recruit players who have played for Ajax, as he did when he was Manchester United coach. Leverkusen on the other hand made a mistake by hiring Ten Hag, but firing him early on was also the right decision before the league progressed further. The results from the two matches he managed provide evidence that Leverkusen is regressing rather than progressing.
I am not surprised at all by the news of ten Hag's dismissal. I am even happy that the Leverkusen management realized their mistake very quickly. I do not consider ten Hag to be a successful coach at all. We have seen Leverkusen's poor performance in both Bundesliga matches. We have not seen any good performance from the team in the pre-season matches either. Ten Hag has failed in both team management and player acquisition. He should be the coach of a team that is not fighting for the title. And whose only target is to avoid the relegation zone. Ten Hag may be successful with these teams.
