Barcelona is not invincible, Chelsea beat PSG in the Club World Cup, and Barcelona didn't even reach the UCL final, so there's no need to be upset because they drew Barcelona, I hate that they drew Barcelona, it shows what they're made of, Barcelona is a great team, but if Chelsea is good they have to play against the good ones, and if they're good they should get through without any problems, in football you can't and shouldn't ever be afraid.
I don't know how some persons are looking at this things, do they think Chelsea can not beat Barcelona, I won't argue that Barcelona is not a good team, we already know that Barcelona is has a team and if we look at Chelsea we can also bold to say the same, trying to see a team less than the other resulted to Chelsea making good effort to defeat PSG in the club world cup, many football lover belittled Chelsea the bit what happened at the end, am not bothered about Chelsea having to face Barcelona, I also know that Chelsea as a team will prepare very well that battle, moresca already know the team his going to come in contact with, football is about expecting the unimaginable.
Both Barcelona and Chelsea fans have high expectations for their teams to win in this match, and I'm not surprised about that because they're both in their best form this season with top players. Looking at their football pattern of play and scoring ability, Barcelona has an advantage over Chelsea. Chelsea is also effective in front of goal, but not to Barcelona's level, likely due to selfish play from their players. I'm certain Barcelona will dominate possession in the match, given their midfield superiority over Chelsea. However, Chelsea's strong defensive marking could be a significant challenge.
