Due to the fact that there are more Belgian teams present in the Europa League, betting wise the Europa League is much more appealing to me!
The Champions League used to be the league of the Champions, now it is just the league of the biggest and richest teams. It was set up to prevent a split of the major teams, when the UEFA was fearing that they were going to create a separate competition.
I doubt it that I even will watch the Champions League game of the only Belgian team present in it, today!
