I actually agree with you because they have lost some of their good players and for any coach to come and take over now, he will have more work to do especially now that the season has started and they have already lost two matches, this is very bad for a team like Leverkusen who many are hoping to compete against bayern Munich. At this stage Leverkusen cannot catch up with Bayern Munich despite the league is just starting because Leverkusen has no focus as it stand now. I like Ten Hag and I really wanted him to succeed with Bayer Leverkusen because of humiliation he have faced in Manchester United but with the look of things it shows that it is not yet time so I will advise him to take a rest before coming back.
If Ten Hag was expected to do a magic is what I still do not understand, I agree that they may have not wanted to take chances with the team but they should not have gone about it in this manner seeing they have a good number of their best players already sold out and the new coach is supposed to build a new team all together, if it were to be that he was given some more time and he still did not make any impact then they will sack him and it will be fine but then again even a new coach will still do same so it is already not really a good move but let us hope for the best for them.
