You could take Alejdandro Bedoya leading FC Nantes in the "I Believe" chant as a sign. After all, he's had a great season for the Ligue 1 club on the field and has become a fan favorite so being a leader in the dressing room wouldn't be a surprise. This could be further proof of it.
Or it could just be a cool video of Bedoya doing a cool thing with his teammates.
It's probably just Bedoya doing a cool thing with his teammates so smile and enjoy it.
