Giovanni Trapattoni has dispensed with the services of Republic of Ireland's old guard as he handed his younger players a chance to impress. Skipper Robbie Keane, keeper Shay Given, central defender Richard Dunne and midfielder Stephen Hunt have been left out of the squad for next month's friendly clash with Serbia in Belgrade, although their absence does not signal the end of their respective careers for their country. Stoke utility man Marc Wilson, Everton's Seamus Coleman and Wigan midfielder James McCarthy, who asked not to be considered for the Euro 2012 finals because his father was undergoing cancer treatment, are among the beneficiaries of Trapattoni's decision to have a look at what he hopes will form part of a new generation for the Republic as they attempt to bounce back from their disappointment in Poland and Ukraine. Republic squad: Keiren Westwood (Sunderland), David Forde (Millwall), Darren Randolph (Motherwell), Marc Wilson (Stoke), John O'Shea (Sunderland), Sean St Ledger (Leicester), Darren O'Dea (Unattached), Stephen Ward (Wolves), Stephen Kelly (Fulham), Paul McShane (Hull), Glenn Whelan (Stoke), Darron Gibson (Everton), James McCarthy (Wigan), Paul Green (Leeds), Seamus Coleman (Everton), Aiden McGeady (Spartak Moscow), Andy Keogh (Millwall), James McClean (Sunderland), Keith Treacy (Burnley), Kevin Doyle (Wolves), Shane Long and Simon Cox (both West Brom), Jon Walters (Stoke).
