The Men of Gwent made it into the semi-finals of the European Rugby Challenge Cup two weeks ago and now face top flight Top 14 team Monpellier in this crucial knock-out battle.
The Welsh Region took on Stade Francais last season and Pau in December of this season, so the squad understand what is required to beat a French team. Crosswell believes that the Dragons can come out on top if they just go there to play.
He commented: "There's no hiding from the fact that Montpellier have a classy side right across the paddock but we just need to go there to play. It's as simple as holding onto the ball and putting them under pressure. If we do that, who knows what can happen and we do have some backs with awesome X-factor but we have to watch our control.
"We need to build our attacks then put them into space because if we don't hang onto the ball then we will have Montpellier running down our throats all day."
Crosswell continued: "I enjoy the battles in the tight. Montpellier have some big boys and I can tell you one thing, they will come with physicality and that's what I'm looking forward to.
"For a lot of boys this will be the biggest game of their lives to date. We will be playing against some of the best fellas in the world so what better chance to showcase yourself than the biggest stage. It's really exciting."
