Munster dug deep for a narrow 27-30 win but they were almost rolled over in
Switzerland as Bourgoin threatened to their quarter-final qualification hopes.
Declan Kidney's men survived the sternest test of their cup defence to retake
top spot in Heineken Cup Pool Four and tee up a winner-takes-all battle against Leicester at Thomond Park next Saturday.
Bourgoin pulled out all the stops and ran in four tries with teenager Matthieu Nicolas
grabbing two second-half scores.
Lifeimi Mafi notched his first Heineken Cup try after 66 minutes, adding to an
earlier Marcus Horan effort and a penalty try, and that haul, allied to 15
points from the boot of Ronan O'Gara, was enough for Munster to maintain their
unbeaten run in the pool.
