Some are a bit silly I suppose but there is one comment on here that me and a couple of work colleagues were talking about earlier this week.
About 60 minutes of "effective playing time" out of 90. :O
Go back 30-40 years and I wonder if that statistic would be different due to the fact referees would let a hard tackle, no, ANY tackle go and there weren't so many girls in the game.
