Coach Alan Gaffney reported everyone to be in 'good shape' ahead of what he termed was, 'a massive game for Munster'. Watching the side go through their paces was Ronan O'Gara his right hand encased in plaster, hopeful to be back in action by the end of the month.
The permutation for Gaffney's side is simple enough - they have to win. Castres lie on 16 points, two behind Munster and they play their final game today against a Neath-Swansea Ospreys side whose interest in the competition has ended.
For their part Harlequins will playing for much more than pride. They will be more than anxious to shake off their indifferent recent form and one presumes they would like nothing better than to re-boot their season with a win against a Munster side they ran right to the wire last time the sides met in Thomond Park.
