It's just that with statistics like this, of course, even though now the coaching and players have begun to update but still Bayern will definitely be superior even though they play home but on the other hand Barcelona have also now begun to improve so there could be surprises this season not the same as previous seasons.
Barcelona have improved from the start of the season and were scoring goals upon goals and still couldn’t win Monaco. I feel they are not yet up to the task to play well in the Champions League because most of the players are inexperienced and that is why i still feel they will find it difficult to play and win against Bayern Munich, Bayern are also struggling these recent games but i know they will always be ready to play against Barcelona. It won’t be an match for either team and it will be an interesting game to watch.
Despite Barcelona's dismal record against Bayern, I'm still very wary about their chances this season. However, I hope they don't approach the game with a revenge mindset as that could lead to more losing matches. If they are focusing on the game itself, rather than proving a point, we might see improvement.
You have a point, approaching the game with a revenge mindset is so unprofessional and will only lead to more losses. Barcelona need to play the game with a free mind without no worries and pressure and they might end up winning.
