Here’s a story you may have heard. Ronaldinho called up Andrés Iniesta before a match against Real Madrid to tell him, shockingly, that he would be moving to their rivals the very next season. He asked Iniesta not to tell anyone this revelation and hung up quickly. The next day, Dinho got all the Barcelona players together to tell them he had called all of them individually to say he was moving to Real Madrid and not to tell anyone else. Only he was not going to go to Madrid, it was in fact a test. And having seen that no player leaked the information, he knew he could trust every player in the squad and thus, that they would teach los blancos a lesson.
