Yes, it's true, there were some changes made in the second half, to secure the condition of his best players. But it's true that it wasn't a big change, because Hansi Flick didn't want to take more risks. He was actually quite confident with his team's performance that they would definitely win, especially since they were ahead in the first half. But after that, he regretted it a bit because he felt he made a few mistakes in the second half until Espanyol's goal happened in the 65th minute.
