For Celtic fans, the sun couldn't have set quickly enough in season 1999/00.

Rangers walked to the SPL title and finished 21 points ahead of The Hoops and Martin O'Neill had been brought to the club to close, or turnaround, that gap as quickly as he could.

After winning the first four games of the season, he took charge of his first derby against the dominant side from the other side of the river, who travelled to Celtic Park as comfortable favourites to win.

They conceded six goals and were blown to smithereens in the sunshine.

An 11-minute blitz saw Celtic fly out the traps and into a three-goal lead, causing the stadium to shake, before Henrik Larsson scored one of the most iconic Old Firm goals of all time in the second half.

Celtic didn't just grab that fixture by the scruff of the neck, O'Neill's side were stamping their authority and laying the foundations for an eventual treble season.

Martin O'Neill, Lubo Moravcik, Paul Lambert and Jackie McNamara reminisce on what is a momentous day in Celtic's history, along with season ticket holder Brian Gilmour and former SPL chief executive and Celtic fan, Roger Mitchell.
