Ten Hag was heavily criticized after losing to Flamengo's youth academy. Now, he absolutely must win this match to avoid a similar setback. The Bundesliga is starting now, and there's no room for error. Every game they play incorrectly will drop points and push them away from the championship. What the Spanish manager has left at Bayer Leverkusen is a team that is contending for the title. If he lets that slide, he won't be in charge for long. I still question his suitability for this role. Perhaps there could be better options.
This is a very valid point, so much criticism was thrown at Erik Ten Hag that I am very sure that at this time he will understand already that he needs to change the narrative with a statement in the next Bundesliga fixture he has ahead. He has a fairly good team of which in the Bundesliga they are considered a top team and all he really need to work on at this point may be mostly with is tactics and his game mentality so he does not look like he is not capable enough, he has been in charge of a bigger team this should not pose do much challenge to him.
