He better settle down for a while after this and work on himself and mental health before thinking of taking another job cause it's very obvious that the job at Manchester United really affected him so badly, before he became the manager of that Team he was one of the best in Europe, the best in the Eredivisie league but post working with Manchester United he's been so shitty and can't even secure another job for a complete season, so sad.
Your thoughts are worthwhile, mate. I suggest that Ten Hag and Jose Mourinho take at least one year break. They are both good coaches, but they lack current tactics to win games. Just like Zinedine Zidane and other managers usually do, let both of them go and learn from top coaches how to apply new managerial strategies. Maybe Pep Guardiola might be the next coach to be sacked because of City's poor performance.
Ten Hag's Leverkusen couldn't even win against Werder, who were down to 10 men. This is why the manager is under intense criticism. It's also worth considering the possibility of his dismissal before too long. Perhaps Jose Mourinho could be an option for Bayer Leverkusen. I'd say he's a coach capable of success in the Bundesliga. He'd be at least more successful than the current manager. It's quite surprising that they conceded two goals from an opponent down to ten men after the red card.
