We should not use ten hang performance at United to judge him because the fact is that United as a team is lacking in quality which has affected them greatly any coach coming to united will always struggle because the structure to succeed is not there when ten hang was at Ajax we saw what he did so I think that he is going to succeed at Leverkusen
If Ten Hag was the problem at Manchester United, why aren't they succeeding right now with a different manager. Ten Hag gave an average performance better than Amorim, despite being his first season at Manchester United, Ten Hag did best during his first season at the club than the new coach.
Till Ten Hag resumes his position as coach of Bayer Leverkusen, it will be clueless to judge without watching him for his first season, Ten Hag might not be the best coach taking over, but not the worse manager for the job.
