There are reasons why the best team in the world lost the Champions League quarter finals today to an upstart. Barcelona played flat, with no one showing flair. Atletico were sharp, precise, technical and quick.
They were outmatched in skill, but they compensated with belief. Most teams are so intimidated by skills-rich Barca that their objective is to limit the humiliation. But Atletico brought a greater work ethic to the pitch. While Messi, Neymar, Suarez and Iniesta lacked their typical flair, Antoine Griezmann showed up with sparkle.
Don’t worry about what you lack. You can make up for it with self-belief.
