This is why I love football because it is full of surprises. PSG was the least club the booker made the favorite in their odd before the competition started last season. They shocked everyone and humiliated all the big clubs that crossed their path during the competition. I will love to see a different club win UCL this season if possible.
Football is more of an entertainment, only for those that have seen it in such manner, because from last season and as you have said, it was never believed that they would have gone that far from the way everything started, which is football for you, i also observe that the same PSG have been panting over the UCL title for long and never got it until their time reached last season that they surprised everyone and made it at last.
Football is mostly unpredictable sometimes the teams you think will achieve a certain position will end up not getting anything even after having the best squad in the team, that is why the level of entertainment and surprises that is in football can be found in any other sports.
PSG has been on the news since they started struggling to achieve the champions League trophy began, they have tried different managers and players but couldn't achieve the trophy but their performance changed last season when they were blessed with good players that were willing to give it all for the team and here they are being rated as one of the best team following their outstanding performance last season.
