What Bayer Leverkusen, the Dutch manager, is trying to achieve is easier than Manchester United. Manchester United faced many tough opponents when aiming for the Premier League title. However, Bayer Leverkusen will now only face serious competition from Bayern Munich. Therefore, a less competitive Bundesliga is more likely to be successful than the Premier League. It could succeed there.
You really think so that what Erik Ten Hag is to achieve with Leverkusen is much easier than he had to achieve with United? Well, if it comes to the competition level then I can agree with you because there is just Bayern Munich they have to battle it out with for the league title unlike the EPL where you have up to 6 teams racing for the title.
