How did Barcelona meet Chelsea for three years in a row?

This is better, because the two teams can qualify in groups. As long as the top two play normally and can join hands to qualify, that is the best! This may prevent them from meeting in the knockout stage. What I want to go to most is the Champions League final, which is a match between two teams, although both teams are my favorite teams. The games played by other teams are not good! Boring! Especially the so-called youth team from the best league in the world mentioned by a famous host, in my opinion, that's all.
