Manchester United's failure to qualify for European competition is enough proof of Ten Hag poor performance, who was unable to manage the team well even though the management had brought in quality players.
We only can say enough evidence of his poor performance as a head coach, if he is sacked by Manchester United. At the end, their club owner, president, sports director and board members will decide to keep Ten Hag or sack him, not bitcointalk members. We only discuss non sense about future of Ten Hag as we can not influence his job at Manchester United.
If I have rights to make decision, I will sack Ten Hag.
Next season, Manchester United will have to settle for competing in domestic competitions and watching their rivals play in the Champions League and Europa League.
They wanted to win Premier League, participate in Champions League but Ten Hag gradually helps them to decrease their ambitious targets to humble ones.
