Tuchel said he was angry at himself for a huge under performance during the Dinamo Zagreb defeat, which was his 100th and final game in charge.

Thomas Tuchel said it was the same story. He looked like a man who didn't know what he was talking about. The decision-makers seemed to agree.
The defeat to Dinamo Zagreb, a side with only two wins from their previous 33 games in the European competition, was an embarrassment. The way in which it was done was more damaging than the result.
There was a repeat of the soft defending after the 2-1 loss toSouthampton. He said that he told them to play harder in the second half. The message was not heard.
It wasn't likely to be forgiven for such defensive under performance. The club invested a lot of money in these guys.
The other end of the pitch was more costly than the other side. His attack was strengthened in the summer. A lack of understanding and ruthlessness had only become more pronounced as a result of Tuesday's game.
It has to come back to the manager and the players. Tuchel did a good job at the club. His legacy will be a positive one, as a result of his success in the European Championship. There were some problems that he couldn't solve. The new owner is the same person as the previous one.
