Montauban welcome London Irish to Stade de Sapiac on Saturday night with Russian international lock and club captain Sergei Sergueev wary of their in-form visitors.
"London Irish are going really well at the moment, high in the Zurich Premiership, whereas we haven't had a great start to the season," he said. "We really need to put some good performances together and try to get a win on home ground for our own confidence.
"This will be a good test for us - we need to kick-start our season and what better challenge than against one of the best teams in Europe?
"At the moment our priority has to be to get our domestic season back on track but we will do our very best in these matches.
"Last year we did well to beat The Borders in Scotland then we narrowly lost to Bath in the quarter-finals. It's always great to play foreign teams and our crowd always gives a good welcome. We have nothing to lose."
