We wait and see how Ten Hag will start the new season with Leverkusen. Can or can not he answer the doubts of people who think that he should not be in Leverkusen? We will wait and see.
Everyone will hope that everything will be fine and Leverkusen will improve their performance. Because previously they have performed quite well, and it will be a problem if Ten Hag has difficulties at the beginning of the season.
As for me, I don't have high expectations for Ten Hag to really do better in his first season. I don't know about other seasons, maybe, but still, I will not be surprised if Ten Hag does better and also wins a trophy in his first season with Leverkusen. I also doubted Kompany before the beginning of last season I thought he would hardly win the Bundesliga in his first season with Bayern Munich but at the end of the season, he was able to lead Bayern Munich to win the trophy.
As far as Leverkusen having quality players, it will not surprise me if Ten Hag wins a trophy like the Bundesliga. But currently, based on his past record at Manchester United, I don't have much confidence in Ten Hag to win the Bundesliga.Next season, the two teams I am expecting to be in great competition with each other are Bayern Munich and Dortmund. Currently, I still believe in Dortmund more than Leverkusen, because it seems that Dortmund have greater players than Leverkusen.
