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. Hansi Flick's guidance could be the boost they need. Nevertheless, it's just a game, and we can't put too much hope into it, but I'm eager to see how they'll perform this season
Bayern Munich doesn't have strong defense and it is same with Barcelona but these two clubs have good attackers. However, I see Barcelona having advantage of Bayern in this match because they are playing in Nou Camp and Barcelona have sharp attackers and quality finisher than Bayern. Lewandowski have no choice than to play against his former team. It will be his pleasure to score against Bayern.
Barcelona and Bayern Munic and indeed every other team in that category do not really care about home or away because they can win any team at anywhere. I don't think home advantage will play a role in the match. However, I still agree with you that Barcelona stand a better chance of winning the match than Bayern Munic when you look at their recent forms. But by their past record, Barcelona have not been so lucky with Bayern Munic as they always suffer terrible disgrace from them. I think Barcelona have conceded one of their higher goals in champions league from Bayern Munic which shows that Munic is doing pretty well when it comes to playing against Barcelona. Going by this, the match is seriously uneasy to predict.
