Ultimately, the expected happened, and Ten Hag was sacked. Leverkusen only lasted two matches against him. They performed similarly in friendly matches, and the team hadn't given any hope. Taking early precautions will benefit Leverkusen.
Forcing Ten Hag to improve a club that has sold all of key players ain't easy. He should be given more time to do that. Expecting him to rebuild back the squad in matter of games is showing how stupid Leverkusen's management is. In the end, he still gets his compensation, and can still eat good everyday.
I hope him back to the Ajax some days. I don't see a better place for him other than it.
Back to Ajax, rebuild his coaching career, and enjoy the money received.
