The Welsh side are in fourth spot with 47 points, six clear of Munster in sixth and though all the pressure is on the home side, Tandy recognises how important this game is. " With four of our last six games away from home we understand the size of the task in front of us but we believe in the ability of this squad to rise to the challenge. It's important that we put in a big performance tomorrow night."
Like Munster, Ospreys have to go to Glasgow. And there's also a trip to the RDS for them to plan. So this game takes on an even greater significance for the title holders whose form graph has been on the rise these past few weeks.
