The only areas really expected to be contentious were at out-half and centre with the usual Ronan O'Gara versus David Humphreys tussle for the number 10 jersey and Rob Henderson vying with Kevin Maggs for the right to partner Brian O'Driscoll in midfield.
Both decision were close calls, according to O'Sullivan, with O'Gara and Maggs just getting the nod.
Henderson must also have impressed the watching O'Sullivan in Stradey Park and once again O'Sullivan admitted that the final decision wasn't easy, "No, once again we have two top class performers, both playing well, that any side would love to have. In the end we went with Kevin but it must be remembered that we're starting out on a long Test programme and we need to have this type of quality player available if we are to achieve our aims."
Anthony Foley was named at number 8 although Victor Costello has been called into the squad as a precaution because Foley is suffering from a slight rib injury. In the replacements the AN Other revolves around Eric Miller who is also carrying a rib injury with Alan Quinlan on standby.
