Nobody should compare Leverkusen and Manchester United currently cause Leverkusen is in a league where there's not much competition and any good coach would succeed there if they can beat or draw Munich home and away then do well against other teams. It's not similar I'm the EPL where there's Manchester City, Arsenal, Liverpool, Chelsea, Tottenham, Newcastle and even other tough midtable teams to deal with. The Premier league is not for the weak.
But Manchester United's performance last season was truly disastrous. I mean, for a team with such a rich history and a former top-four finish a few years ago, they finished 15th in the final standings. On the one hand, we can't compare Leverkusen to United, as they're both from different leagues. However, I still think United lost not only to elite teams but also to underrated teams. The Bundesliga isn't as competitive as the Premier League. In the Bundesliga, if you can beat or draw against Bayern Munich, your chances of winning the title are very high. But I hope other teams like Dortmund or Frankfurt can challenge Munich to make the league competitive.
