by fans. The club's supporters also publish fanzines such as The Gooner, Gunflash and the satirical Up The Arse!. In addition to the usual English football chants, supporters sing "One-Nil to the Arsenal" (to the tune of "Go West"). There have always been Arsenal supporters outside London, and since the advent of satellite television, a supporter's attachment to a football club has become less dependent on geography. Consequently, Arsenal have a significant number of fans from beyond London and all over the world; in 2007, 24 UK, 37 Irish and 49 other overseas supporters clubs were affiliated with the club. A 2011 report by SPORT+MARKT estimated Arsenal's global fanbase at 113 million. The club's social media activity was the fifth highest in world football during the 2014–15 season. Rivalries Arsenal's longest-running and deepest rivalry is with their nearest major neighbour, Tottenham Hotspur; matches between the two are referred to as the North London derby. There also exists a rivalry between Arsenal and Chelsea. In addition, Arsenal and Manchester United developed a strong on-pitch rivalry in the late 1980s, which intensified in the early 2000s when both clubs were competing for the Premier League title. Mascot The club mascot is Gunnersaurus Rex, a smiling, 7-foot-tall green dinosaur, who first appeared at a home match against Manchester City in August 1994 (or 1993). He is based on a drawing by then 11-year-old Peter Lovell, whose design and another similar idea won a Junior Gunners contest; his official back story is that he hatched from an egg found during renovations at Highbury. The same person, Jerry Quy, has been inside the suit from the start; in early October 2020, as part of cost-cutting brought about by the COVID-19 pandemic, the club made him redundant from that and his other part-time job in supporter liaison, together with 55 full-time employees, although they later said Gunnersaurus could return after spectators were allowed back in stadiums. An online fundraiser was begun for Quy, and Mesut Özil offered to pay his salary himself as long as he remains with Arsenal. In November 2020, in advance of COVID-19 regulations being relaxed to allow supporters to attend home games from 3 December, Arsenal announced that Gunnersaurus would return, to be played by a roster of people that could include Quy if he wished. Ownership and finances The largest shareholder on the Arsenal board is American sports tycoon Stan Kroenke.
