I speculate that Ten Hag will give his all at the start of the season when he first takes charge of Leverkusen. After that, in the following season, he will likely experiment again, as he did at Manchester United, and failure may be repeated. However, this is just speculation, and there is no guarantee that it will happen. Ten Hag certainly must realize that he is in a team with small finances. Therefore, he must be more careful when bringing in new players.
