Saracens look to set to break their own world record when they host Harlequins at Wembley on Saturday.
Sarries currently hold the record with 83,671 in the same fixture back in March 2012 but, with already 80,000 tickets sold, Nigel Wray hopes they can beat it on Saturday.
He said: “With luck, we’ll set a new world record for the largest crowd ever to watch a rugby union match in England and the largest crowd ever to watch a club rugby union match anywhere in the world. Saracens at Wembley has become a calendar event in London, a great day out including great rugby and a great show at a great stadium.”
