I think Ten Hag will be successful in this German adventure. A manager who won trophies with Manchester United will also be successful in Germany. The Bundesliga is a major goal for Leverkusen, and I hope they win. Bayern's wins every year make the league less exciting.
Erik Ten Hag didn't have a fantastic time in the Premier League. Although he led Manchester United to win the EFL Cup in 2023 and the FA Cup in 2024, we can say that these are not major competitions. Maybe they had a more eventful time in Ajax, where he won three Eredivisie titles and two KNVB Cups. We cannot certainly say that the Dutch coach will have a good time in the Bundesliga because it would be his first time in the German League.
