However, many players are leaving Leverkusen before the next season, including Jonathan Tah, who left as a free agent, Frimpong, who joined Liverpool, and Florian Wirtz, their key player, who will be difficult to replace because Ten Hag lacked the experience to bring top players to the team because all of the players he signed while at Manchester United didn't work.
Thats what i already have written and are my opinion too , but Ten Hag was good at Ajax times.
And te next thing is that Leverkusen is a different team Manchester United and its possible that young and other players getting the chance to shine.
But it will be very hard for Leverkusen to compensate all of the players who left Leverkusen.
