Indeed Leverkusen lost good talents this summer, they lost Frimpong, Tah, Wirtz which will have impact on the team’s performance, their performance might actually drop next season putting the new manager Erik Ten Hag under much pressure to stop this from happening. I think the big question now is will the infamous Erik Ten Hag be able to prevent this from happening?
The replacement of this players are very important because they don't need any players they would be testing if they can help them this season, actually any team that's selling some best should already have plans of signing the ones that would be important than the previous ones because if a club get rid of players that was doing remarkably for them to others that doesn't even have a good record might be destroying what they have already, so actually it could have been a better plans for Bayern Leverkusen to sell some unimportant ones than this.
