London - Munster saw off Welsh region the Ospreys 18-11 on Saturday to set up an all-Ireland Celtic League final at their Thomond Park home ground against European Cup finalists Leinster.

Danny Barnes's first two senior tries for Munster, plus eight points from the boot of Ireland flyhalf Ronan O'Gara, saw the hosts into the final.

The Ospreys stayed in touch through Dan Biggar's boot and a 79th minute try from Richard Fursell before Barnes's second try sealed Munster's victory.

Defeat ended the Ospreys' hopes of becoming the first team to win back-to-back Celtic League titles and set Munster up for a clash with Leinster, who will hope to complete a double at Thomond Park on May 28 after facing English club Northampton in the European Cup final in Cardiff a week earlier.

Leinster though could be without Ireland captain Brian O'Driscoll for both finals after the talented centre suffered a leg injury during Friday's 18-3 Celtic League semi-final win over Ulster.
