Munster look unstoppable. They ground out a win over Cardiff Blues last weekend with sheer brute force up front, and there aren't many who would predict a different outcome at Thomond Park this weekend.

Incredibly - Munster have never lost a Heineken Cup match at their fortress venue in 12 seasons of European rugby. It is unlikely that Dai Young's Cardiff Blues will be the team to break that record.

The Blues have come close this season, but are still looking for cigars - as the old saying goes.

The Welsh side beat Bourgoin in Round 1, pushed the Tigers hard in Round 2, and were it not for a bounce of the ball here and there, could have turned over Munster in Round 3.

But, with just five points from three matches, qualification for the final eight now seems virtually impossible. Munster by contrast are top of the Pool, and full of confidence.

David Young has selected a team that shows four changes for this Saturday's Heineken Cup match against Munster at Thomond Park.

Nick Macleod gets a well deserved start at 10 having waited patiently for a starting opportunity, while Tom Shanklin is brought in from the wing to partner Jamie Robinson in the centre which gives the near ever present Marc Stcherbina a spot on the bench.

John Yapp starts in the front row as Gethin Jenkins was not considered for selection after injuring his calf in the home match, however he should be available for the Ospreys match. Bradley Davies also gets a start in the second row after

James Goode picked up an ankle injury in last Sunday's defeat and is expected to be out for up to 14 days.
