#1. Real Madrid
Ever since Barcelona claimed their last Champions League trophy in 2015, their eternal rivals, Real Madrid have dominated the European tournament, winning the last 3 consecutive editions of the competition - something that hurts the Camp Nou faithful.
Los Blancos' success in the tournament over the past few years have provoked Barcelona and the La Liga champions will be coming all out to dethrone them this season. This could as well be made easy after the Galacticos lost their talismanic forward, Cristiano Ronaldo to Juventus this summer.
Therefore, the desire to end Real Madrid's dominance on the European throne is another factor that could inspire the Catalans to claim the prestigious trophy this season.
