I feel the same.
At an club and international level, these Bayern players have caused Barca players so much misery over the past few years.
It just feels like it's time to finally destroy them.
In similar cases two things can happen:
1. we can play up to 120% focused because we want a revenge. And eventually win.
2. but also, because some players lost a lot of times against this opponent, if something starts wrong (like losing 0:1 or 0:2), there is a chance of a complete system meltdown (giving up too soon)
For example, try to remember how our team looked without ideas but also without any self belief when we needed a response, in last year's matches against Atletico (we played 5-6 times against them, and players lost a self belief)
Or how we played in the last 10-20 matches in the last Season.
Whenever we conceded a goal, we gave up, we were lost. As if players thought: "We can't make it. I am giving up."
(I know. A different team, a different coach, a different era)
But revenge is a dangerous thing.
And similar matches with 120% of emotions/revenge feelings can easily turn in seconds into either:
1. extremely successful
2. or horribly wrong
