One of the matches of the weekend sees the battle for pole position in Pool 2 hot up.

Dean Ryan’s Gloucester opened the tournament last week with a thrilling first half performance to blow away Ulster at Ravenhill and confirm their status as Pool front runners.

But if they are to keep their momentum going they will have to first get past the Magners League champions.

The star-studded Ospreys got off to a winning start at the Liberty Stadium but failed to gain the valuable bonus-point win over Bourgoin.

They will have to raise their game if they are to emerge victorious at the intimating Kingsholm.
