signed in 2007. In July 2014, it was announced by the RDS and Leinster rugby that a design competition was being held to develop the arena into a 25,000 capacity world-class stadium, with work expected to commence on the redevelopment in April 2016. The selling of naming rights to the arena will be a key component in funding the project, with an initial budget of €20,000,000 being proposed. Aviva Stadium For bigger games where the RDS does not have sufficient capacity, Leinster play their games at the Aviva Stadium, which has an all-seater capacity of 51,700. These are often key home games in the European Cup or United Rugby Championship games against domestic rivals. In 2010 they first played a home league game against Munster, the first time the stadium sold out, and then against ASM Clermont Auvergne. Leinster defeated Leicester Tigers at the venue in the 2010–11 European Cup quarter-finals and went on to beat Toulouse in the semi-finals, also held at the Aviva stadium on 30 April 2011, en route to winning their second European Cup. The following season Leinster hosted Munster, Bath and Cardiff at the Aviva Stadium and remained unbeaten at the ground until December 2012 when they lost 21–28 to ASM Clermont Auvergne. Donnybrook Stadium Leinster's traditional home over the years has been Donnybrook Stadium in Donnybrook, Dublin 4. Donnybrook consists of a single covered stand and three sides of open terracing. A move across Dublin 4 to the RDS Arena for Leinster was needed to accommodate growing crowds, as the 6,000 capacity stadium had become too small. For this reason, Leinster have signed a long-term lease with the Royal Dublin Society to play home games at the RDS Arena. Donnybrook has since, been improved as a venue with the reconstruction of the grandstand in 2008 and remains an important venue for rugby union in Dublin. Due to limited space, it is unlikely that Donnybrook will undergo further redevelopment. Leinster A play their British and Irish Cup games in the stadium and the senior team have continued to hold certain pre-season friendlies in the stadium as well as most Leinster schools cup matches being held at the venue. Supporters Before the advent of professionalism in the Irish game, provincial rugby games were generally poorly attended. During most of the 1990s, Leinster matches regularly attracted crowds of about 500 to 2,000. The decision to structure the
