Montpellier 34 Cardiff Blues 21: match report But from there it was virtually one-way traffic and Montpellier ran riot with Timoci Nagusa, Rassie Van Vuuren and Yoan Audrin all crossing for tries. Cuthbert hit-back for the Blues but Johnnie Beattie wrapped up the bonus-point. Rhys Patchell chipped away at Montpellier's lead but it was not enough for the battling Blues. Meanwhile, Shane Monahan scored four ties for Gloucester in a one-sided top-of-the-table clash against London Irish in Pool One of the Amlin Challenge Cup. Gloucester are now seven points clear at the head of the pool following their 47-3 victory at Kingsholm. Freddie Burns was responsible for 17 points, converting four of Gloucester's six tries - Rob Cook and Dan Robson were the other scorers - and added three penalties. London Irish now have to hope that Gloucester slip up to stand a chance of getting through to the knockout stages. London Welsh are all but out of the Challenge Cup after a 27-13 defeat at home to Grenoble. The Exiles lost last week's Pool Five encounter at Grenoble but were later handed the game because their opponents fielded an ineligible player, but they are unlikely to get such a lucky break this time. The result leaves Welsh third in the pool, 10 points behind leaders Stade Francais. Horacio Agulla scored three tries as Bath thrashed Calvisano 39-5 in Italy to keep up their perfect record in Pool Four.
