Looking at the line up of the semi finalists, I feel that Barcelona are the favourites to win which would do the tournament justice as Barcelona are the only side left that has participated in the tournament by entering it the proper way i.e. through winning the top flight division the previous season.
If UEFA are truly serious about branding the tournament as "Champions League" or "Club Champions Cup", then the tournament should go back to the way is was pre-1992, where the pre-requisite to participate was that a club had to win the top flight division the previous season. Nowadays, it seems to be rigged in favour of the big and fashionable sides even though if they have not won any silverware at all during the previous season. Yes, there have been a few odd flash in the pan sides such as Blackburn Rovers, Leicester City, Sturm Gratz, Artmedia Bratislava, and APOL Nicosia who gave a good account of themselves as well as winning their respective top flight divisions, but instances like this do not happen very often.
