The UEFA Champions League quarterfinals came to an end this week and now, only four teams remain in pursuit of the biggest club trophy in world soccer.
Both Paris Saint-Germain and Barcelona survived ferocious comeback attempts to advance to the semifinals. Hansi Flick's side had a four-goal advantage going into the second leg vs. Borussia Dortmund, but the Germans didn't go away quietly; on the back of Serhou Guirassy's hat-trick, the tie ended with the Catalans advancing 5–3 on aggregate.
PSG were up 5–1 on aggregate at one point in the quarterfinals, but Aston Villa scored three unanswered and had the Parisians with their backs against the wall in the second leg at Villa Park. Luis Enrique's men held on to win the tie 5–4 and continue their pursuit of the club's first ever Champions League trophy.
Arsenal brilliantly dominated reigning champions Real Madrid over both legs to win the tie 5–1 and return to the semifinals for the first time since the 2008–09 season.
Inter Milan had to defend until the final minutes, but were overall better than Bayern Munich and booked a spot in the semifinals after defeating the Germans 4–3 over both legs.
Now that the Champions League semifinals are set, Opta's supercomputer ran predictions to see who the favorites are to win the competition. Before the quarterfinals, Opta had Barcelona as the odds-on favorite to win it all. However, there's been a change at the top ahead of the semifinals.
