It won't be easy for Ten Hag because several players have left the team which will certainly impact Leverkusen's performance next season, Ten Hag's failure at Man United will certainly always be remembered and that is what causes many doubts now for Ten Hag, I am the same, I doubt that Ten Hag can continue Xabi Alonso's work.
The failure at Manchester United has really tinted his reputation and now the doubts about his ability to get Leverkusen to doing better than they are already, this is his chance for him to prove his ability to do better than. What have been known of him in Manchester United all this years. I do not want to doubt his abilities in Leverkusen by trying to compare his past performance in his former club, after he left Manchester United he had some time to rest and he must have used that time to carefully examine his performance so far so I believe he may do better in Leverkusen.
I think when all the eyes and all the negative words are always at you then it gets somehow difficult for the person to perform with all his heart and brain. And for now the person is Eric Ten Hag who is facing all this stuff. But this is the time of really a test for him how he got rid from all of the criticism. And for now there is no capacity for any little mistake for him. He has to be proven himself as the best coach. Who drove the team from best to bestest. Only in this situation his career is safe otherwise what he is facing already is more than enough. And for the fans and viewers i think with critics a little bit of motivation is also there. Because it is not necessary that the same things happen every time even at different places. Different places different changes should occur.
