Taulupe Faletau knows his Dragons side face a tough task if they are to beat Montpellier in their Challenge Cup semi-final later this month.
After getting the better of Gloucester in Saturday's quarter-final at Kingsholm, the Welsh team secured a successive last-four appearance.
While delighted, Faletau admits that their next hurdle, against the French giants, is a difficult one after watching their victory over Sale.
"We got to the semi-final last year and it did not go well on the day, but hopefully we have learned from that," he told EPC Rugby.
"Most of the squad watched Montpellier's game against Sale, they are massive men and a very physical team and we are going to have to try and stop that and apply our game.
"It is going to be very tough but anything is possible. We were written off before the quarter-final and we will attack this game just as we did that one."
He added: "We always back ourselves, just as we did with the late penalty at Gloucester. We could have kicked the late penalty for the draw but we were brave, we went for the win and we pulled it off.
"There was some relief afterwards, we had not won for a while so it was great to not only get the win but to do it in a quarter-final away from home against the champions."
