Montpellier struck a big blow on the road to the London Irish ground in the opening of the Champions Cup.
The Héraultais had however joined the locker room at half-time with a handicap of 9 units on the scoreboard after a missed start to the match due, in particular, to a yellow card inflicted on Forletta (25th).
But the red card addressed to Creevy (33rd) upset the face of the meeting to the disadvantage of the local team.
Returning from the locker room, it was a conquering Montpellier who found the lawn, dominating in impact and author of three tries, by Darmon (52nd) Becognee (61st) and Darmon (65th), again, for an improved final success 32-27 which ideally places the men of Philippe Saint-André before the second day.
