-snip- Managing a big club that has quality players is not a guarantee a coach will succeed in that club if the coach fails to figure out good tactics that will help him get the needed results.
Good players do not guarantee that they will qualify from the group stage, or even become champions, it's true. Because the performance of players always changes every time, physical factors and strategies that cannot be executed well during the match on the field have a significant influence on the final result. There are many histories of good teams in the domestic league failing in the UCL, this is enough to be part of the facts that cannot be avoided. Although Bayern performed well so far and maybe become favorites, I hope there is a team that is beyond expectations that can reach the final like last season, when the quarter-finals to the semifinals were unpredictable results.
