Perhaps anticipating the nightmare Barcelona were about to endure against Bayern Munich, Dani Alves took out his nervous energy on the hair of a young mascot. As the two teams were lined up for the Champions League anthem, Alves became a hair stylist as he tried to make the kid's blond locks stand up in some sort of makeshift mohawk.
The kid just stood there, looking straight ahead with a blank smile on his face that said, "What...uh, what is this guy doing to my head right now?"
Of course, Barcelona went on to lose 4-0, so this should be a lesson to professional footballers everywhere. Nothing good comes from messing with a mascot's hair.
