This record was set during the match between Saracens and Harlequins on 25 March 2023, which attracted a combined peak television audience of 1.516 million people, accounting for 7.1 per cent share of all British TV viewers at that time.

[8] Subsequently, for the 2009–10 season, the club announced it would stage three of its Premiership home games – as well as a special exhibition match against South Africa – at Wembley Stadium, in a bid to boost supporter numbers.

[11] In 2019, Saracens announced an initial five-year stadium partnership with Tottenham Hotspur to host fixtures annually, under the new banner of 'The Showdown', at the Premier League club's ground.

[15] Once full-capacity crowds were allowed to return to stadia at the start of the 2021–22 season, Saracens finally held their first game at the Tottenham Hotspur Stadium in March 2022, against Bristol.

[19] After setting a club attendance record in their inaugural appearance at Wembley Stadium, Saracens announced that they would stage two additional home fixtures at the ground during the 2009–10 season.

[21] For the club's third and final visit to Wembley Stadium in the 2009–10 season, Saracens faced rivals Harlequins for the first time, establishing the basis for the showpiece fixture's future identity as 'Derby Day' and 'The Showdown'.

[24] Saracens and Harlequins contested the first incarnation of Derby Day at Wembley Stadium in March 2012, with the visitors emerging as the winners by 24–19 – the first and, to date, only away victory in this showpiece fixture.

[29] In front of a new world record crowd of 83,889, which exceeded the figure set in the same fixture two seasons earlier, they triumphed over Harlequins with a final score of 39–17.

For the third consecutive meeting between the two teams at Wembley, a new world record was set, as 84,068 supporters attended to create the biggest ever crowd for a rugby union club match.

[48] A new individual record was also set during the match, as Saracens fly-half and captain Owen Farrell, on the occasion of his 250th appearance for the club, brought his total career points tally against Harlequins to 278 – the most ever by one player against a single Premiership team.

[49] As with the previous year, the fixture's simultaneous live broadcasts on ITV and TNT Sports broke Premiership television audience records, this time drawing the highest average viewership in the competition's history, at 913,000 people.

[51] In September 2009, Saracens scheduled a special exhibition friendly against South Africa at Wembley Stadium in November – coinciding with the 2009 autumn internationals, during which the Springboks had lined up a tour of the Northern Hemisphere.

[52] The announcement followed investment into Saracens earlier in 2009 by a South African consortium, which included former Springbok captains Francois Pienaar and Morné du Plessis.

[56] Overcoming a 12-point half-time deficit, Saracens eventually claimed a 24–23 victory, with former Springbok fly-half Derick Hougaard kicking the winning drop goal for the London club.

[57] To date, this remains the only rugby union fixture to be contested between Saracens and South Africa, despite suggestions of a potential rematch over the subsequent years.

[58] Another exhibition game between the club and South African side Stormers at Tottenham Hotspur Stadium had been announced for an unconfirmed date in 2021, but this event ultimately never came to fruition, because of the COVID-19 pandemic.

[72] For the second year in a row, the fixture recorded the largest ever crowd for a Saracens women's home match, exceeding 3,000 attendees at the StoneX Stadium for the first time.
