Also on Friday it's the battle of the capital city teams as Edinburgh host Leinster at Murrayfield, a ground where the home team has not lost in their last six Magners League outings. The two teams have met on three occasions already this season - once in the Magners League and twice in the European Cup - with Leinster victorious each time, and their confidence is bound to be high following their success in Europe last weekend.

Saturday sees a West Wales derby when Ospreys travel to Llanelli to face Scarlets at the Parc y Scarlets. Ospreys will be hoping to put an end to their poor run of form that has seen them win just one of their last four matches: 16-13 in Ulster on 3 April, whilst Scarlets will face them with confidence having won their last four home games against fellow Welsh regions.

The round wraps up with the all-Ireland clash between Munster and Connacht at a sold out Thomond Park also on Saturday. Connacht turned over Munster 12-6 at the Sportsground on 28 December but have never managed to achieve back to back wins over their illustrious neighbours. Munster will be a tough opponent and are in a rich vein of form as shown in their impressive European victory over Ospreys last Saturday.

NOTE: The remaining Round 15 fixture between CARDIFF BLUES and NEWPORT GWENT DRAGONS has been postponed due to Blues' involvement in the Anglo Welsh Cup.

Munster's rich run of form continued with an eighth straight win over the Ospreys in the European Cup on Sunday. The Magners League leaders record against fellow Irish teams this season is a less than impressive won 2, lost 3.

Connacht's 39-17 victory at home to the Dragons last time out in the Magners League included their first try bonus point in the league since January 2007. Connacht have won just once on the road in the Magners League since September 2006: 13-11 at the Dragons on 18 April 2008.

Connacht turned over Munster 12-6 at the Sportsground on 28 December but have never managed to achieve back to back wins over their illustrious neighbours.
