The man approaches the star and asks "Kenny you looking forward to the game?" to which the footballer says "aye" before walking away. 

The cameraman then shouts: "You looking forward to getting pumped?"

He follows the star around the isle taunting "5-1 mate, hail hail."

He shouts "Hail Hail" again before continuing: "Kenny Miller's a w**k!"

The shocking 28-clip has outraged Celtic and Rangers fans after it appeared on a social media page on Facebook today. 

Stuart Carruthers said: "from a Celtic fan this is poor, Kenny Miller is a decent bloke and no one deserves to be abused like that..."

Finbar Bryson said: "Kenny Miller is a Decent Guy. I've bumped into Him a fair few times over the years and he's always happy to chat away. No need for the Name Calling."

Shaun Smith said: "No wonder footballers ignore so many fans now."
