Cardiff Blues back-row Josh Navidi insists the Welsh region must take on Toulon with all they have got when they face their Pool rivals in Nice.
The Allianz Riviera will host the reigning Heineken Cup champions and the Blues in what is a pivotal game in the context of Pool 2's final outcome.
Navidi, who was part of the shock 19-15 win over Toulon at Cardiff Arms Park in October, believes they have a real chance of doing the double.
"It's always hard out in France, but we are all looking forward to it. Last year we came close to them and we now need to go out and back ourselves," he told the region's website.
"We scored four tries last year and we need to go and play like that again. It will be a hard game and the atmosphere will be something else.
"It's a massive challenge for us away at Toulon. The players they have are unreal, they have all the stars, but if we dig deep and put them under pressure you just never know.
"We have to go out and take it to them, there is no point letting them control the game.
"People will say we are underdogs with no pressure, but there is always expectation when you play for Blues. We back ourselves and will take it to them."
Cardiff Blues enter the European clash following a much-needed RaboDirect PRO12 triumph over the Dragons that Navidi admits was crucial for their league hopes.
"We needed that result. Last week was disappointing because if we had got a win down at Rodney Parade we would have moved up the league and overtaken a few teams," he said.
"We had to win back on home soil and not giving away a bonus point is also a positive.
"The forwards in the second half against Dragons were outstanding and the backs controlled it.
"We now need to keep building on that in the RaboDirect PRO12 and now going into the Heineken Cup, as we have a chance of qualifying."
