It seems the doubts surrounding Ten Hag are starting to be confirmed, as he hasn't been able to lead Leverkusen to victory. The pressure will only increase as time goes on, the only way to retain his managerial position for a longer period is to quickly win the next match. Otherwise, anything Ten Hag says will seem like an excuse, and Leverkusen fans won't accept it.
This situation will be even more difficult for Ten Hag, as he isn't a coach with great tactical talent for a team like Leverkusen. Furthermore, Leverkusen's current players aren't particularly talented with the ball, so his situation will only worsen if Leverkusen starts struggling to win. I was already skeptical of Ten Hag before the season began, as his Premier League career has been less than solid, so this should at least be a fairly accurate assessment for Leverkusen before hiring him as manager this season.
