It doesn't matter who is better at the time TBH. The key thing is to have the best player for the position return to his form. He won't ever do it on the bench, especially the stars who generally turn around the games they're not expected to influence when on goal drought or a dip in form. Cruel to backups, but hey, that's how the cookie crumbles.
People are boring.
best team in the world in 2014 was atletico. without costa's injury for the final, they would have won it in 90 mins. for 2016, leaning towards either of barca/bayern. barca hit the wall, while bayern were unlucky to not make the final.
