Galvão Bueno is the iconic voice of Brazilian football, narrating the national team's biggest moments on Globo for decades. His on-air musings became a genre of their own, and 'ninguém sabe' — his wry admission that nobody can predict football — turned into a beloved catchphrase. Brazilian fans clipped it into WhatsApp audios and video edits, where it now works as a universal punchline for uncertainty, failed predictions and gloriously unpredictable matches.
