Ten Hag is as much the opposite of Alonso as he could be, there are literally zero similarities between the two coaches. I think it is a mistake, but who knows maybe it is owed to the fact that not too many coaches are available at all.
Erik ten Hag is a pretty good manager. Take a good look at his Ajax days, he had no such issues with communication and whatever they say about ego. Interviews with his players also confirmed that. He did well during he first season with Manchester United, one thing people should know is that he has the best winning rates after Sir Alex Ferguson. That said, I'm one hundred percent certain he will be successful with Bayern Leverkusen.
Erik ten Hag is notca bad manager if you check his achievements during his days at Ajax but coming to Manchester United you can't compare what he's done in Ajaz to Manchester United because after his first season with United the his rest days was a disaster because he couldn't get the United team to a better position other than issues upon issues. Bayer Leverkusen is a team that has good players I believe he's going to succeed there if he could manage the players well and not get into any problems relating to his choice of players in the team.
