Expectations are not a problem for everyone because every prediction is not all correct even if we reflect on last season's achievements achieved by a team. And if we have to wait for the season to start so that everyone can talk about Leverkusen, I think that's quite old thinking because here everyone is discussing even though we don't invite certain people to reply to a discussion that we write. Because everyone certainly knows how hard it is to compete in the Champions League so the pressure, luck and skills of each team will really be tested in the Champions League.
You are right, expectations will always exist in the world of football, where everyone will start to have expectations because they saw the game of a very promising club in the previous season and they start to expect that in the next season they will also do the same, namely play as well as possible.
However, this is the Champions League and as said here every pressure will be greater and they have to be ready for all of that. And actually it's not just them, but all clubs must be prepared for the pressure they will receive. But here is the difference, when a club is used to it here, mentally they will be better trained because they are used to it, but for clubs that are not used to it, it will be a challenge for them, how can they withstand every pressure that exists.
This is a job for every coach, where they have to ensure their squad is in excellent condition.
