Meanwhile, Leinster Rugby are delighted to announce that David Lloyd Health & Fitness Riverview in Clonskeagh will become the new administrative home to the Leinster Senior team. The facility, which already incorporates a gymnasium dedicated exclusively to Leinster Rugby, has a private entrance and will include offices, meeting rooms, team rooms and the existing private "Leinster" gymnasium has been tripled in size.
The Riverview complex, which won the prestigious 'commercial club of the year' award recently, also features aerobics studios, a cafe restaurant and licensed bar with free internet cafe, indoor and outdoor swimming pools, indoor and outdoor tennis courts, squash, badminton, rehabilitation centres and medical facilities, conference facilities and a spa.
The team will continue to use Old Belvedere RFC and the newly relaid back pitch in Donnybrook for training purposes. The move is expected to take place next week.
Speaking on Wednesday, Leinster Rugby Chief Executive Mick Dawson said: "I am delighted to announce that Riverview will become the new administrative home for Leinster. This is another step aimed at preparing the squad in the best possible way in a professional environment. I would also like to thank the executive, office staff, groundstaff and members of Old Belvedere for their wonderful assistance in facilitating Leinster's administrative needs in recent years."
Paul Taylor, Director of David Lloyd Riverview, added: "This is a very exciting time for both organisations and I look forward to continuing our ongoing partnership with Leinster Rugby well into the future."
