The number of Glasgow Celtic supporters who travelled to Seville in May 1993 to watch their team get beaten 3-2 by Porto in the UEFA cup final.
The initial estimate of the number of travelling supporters was 30,000 , however this has now risen to over 6,000,000.
At this rate it is estimated that by the year 2012 everyone in the world will have attended this match.
John Paul says he was in Seville.
