Here we go again... another prediction of yet an event that's has not even started, Barcelona and Realmadrid are not the only team that will be playing at the UCL I don't know where the comparison and (disrespect) is actually coming from. There're tones of matches to witness so I won't come to conclusion very early but it's still a "good chance"--easy to buy actually.
Next UCL will be quite interesting as each team will have to put in more effort just to qualify and stand chance... currently almost everyteam is building their squad just like realmadrid but realmadrid seem to be the leading so far.
Barcelona is an overrated team, many people still can't accept the reality if a team who perform good in the past has no guarantee will perform good in the future, Barcelona is a team that play well in the last decade, now they're nobody.
In this generation, there are only Real Madrid, Manchester City, Bayern Munich and Inter that can consistent enough than other teams. I will not be surprising if I will see these teams in semi final.
