I'm very surprised at the result of Barcelona game today, I at some point couldn't accept the result almost immediately because I almost couldn't believe it because I have seen this same team won against tough and bigger team that they got landslide victory and now they are playing against a small team that they should have won very clearly but they couldn't, well this is football and almost anything can always happen. This should be one of their few losses they have suffered this season.
Even taking this defeat into account, Barcelona has 33 points out of 39 possible, which is a very good indicator (84%), so I would say that this defeat was logical, since you can’t outperform forever. There was a return to the mean and the bookmakers were expecting it, Barcelona's odds of winning were estimated at 1.97, these are very weak odds for a team that dominated so much.
