Blessing Awodibu is a social media sensation and a huge Mayo football fan.
The Castlebar native is a huge hit on Facebook and Instagram and on a recent trip to Shanghai, he serenaded passersby with songs about his beloved county.
The clip shows him convincing a 'Dublin fan' to remove his sky blue jersey and shout 'Mayo for Sam'.
He's not a man you want to argue with. Watch below:
