WASPS will take a huge stride towards the Amlin Challenge Cup quarter-finals if they can win in Grenoble tomorrow night.

The black and golds have won both their group games in the competition so far to top Pool 3 by four points.

Another victory tomorrow would just about end Grenoble’s challenge and go a long way to making the return fixture something of a formality.

Wasps director of rugby Dai Young said: “I think the outcome of the first game will have a baring on the second one and what their attitude is.

“If we go there and get something out of the game, I would have thought they’d be less keen to come over here and give it everything.

“But I’m sure if they get a good win under their belt it will put us under pressure for the home game because they’ll come gunning for it.”

However, Young is taking nothing for granted.

He said: “They’re a decent team, that’s for sure. They’re a big, strong team and we know we’re going to have to play to our best.

“Going away from home, any win in France is always a good win and we’re not underestimating the difficulty of the game.

“It would be nice to be going to these places with some of our more recognised campaigners, but we go with what we’ve got and we’re still confident if we play to our potential that we can come away with something.”

Having already beaten Bayonne, Wasps would put themselves in the box seat for the knock-out stages with a pair of wins over Grenoble.

Young said: “We’re quite proud to have got to the quarter-finals in the last two seasons and lost to the winners twice in Biarritz and Leinster.

“We’ve done quite well in this competition, but this is by far the toughest draw we’ve had with two French teams in the group.

“Away victories are always going to be tough, but it’s in our hands.”

Meanwhile, English clubs could still play in the Heineken Cup next season after their French counter-parts backed away from a breakaway competition, the Rugby Champions Cup, in favour of remaining in the Heineken Cup.

They did so on the proviso that English clubs follow suit, which they will do if a new structure is put in place in time for the 2015/16.

"If somebody outlines the structure, we could look at it," said Premiership Rugby chief executive Mark McCafferty.
