Bath boss Steve Meehan wants his team to "play without fear" in the Heineken Cup quarter-final clash against Leicester.

Bath head to the Walkers Stadium following some average Guinness Premiership form that has seen them win just four of their last eight league games.

The latest loss was a 19-3 home reversal to Harlequins six days ago, suggesting Bath's work is cut out as they target a repeat of their 2006 Heineken quarter-final victory over Leicester on the same ground.

"We need to arrive at Leicester and play without fear," said Meehan.

"It is a one-off cup match, and we have to go out and see how good we can be.

"What happened last weekend certainly won't force us into our shells. It's a big prize, and it is worth fishing for.

"Let's go and see if Bath can repeat what they did there a few years ago.

"We've got to put aside what happened against Quins and get back to playing the rugby we know we can play. Sometimes a bad dress rehearsal can mean a good performance on the big day."

Bath will be relieved their fly-half, South African World Cup winner Butch James, was cleared by Rugby Football Union disciplinary chiefs earlier this week after being cited for an alleged stamp on Wasps centre Riki Flutey.

But Leicester, seeking a sixth Heineken semi-final appearance, have lost the services of England prop Julian White following his sending-off last weekend.

Pre-tournament favourites Toulouse face a testing encounter against Cardiff Blues at the Millennium Stadium.

The French Championship leaders, chasing a record fourth European title, will meet opponents unbeaten in this season's tournament and further boosted by reaching next week's EDF Energy Cup final.

"These are exciting times for us," said Blues head coach David Young.

"There is a lot of anticipation and excitement in the squad, and although it is a massive challenge ahead, it is one we don't fear."

Toulouse battered the Blues 41-17 in last year's quarter-finals, but Young added: "I believe we are a far better team now.

"We have matured as a squad, we have a harder edge and we are more used to playing big games on the big stage.

"Last season when we reached the Heineken Cup quarter-finals it was a big achievement, but we must not settle for that this time. We must have the determination and self-belief to go further.

"It is a big statement, getting to the quarter-finals in successive seasons, but Toulouse represent another step up the ladder."

Sunday's action sees holders Munster installed as clear favourites to beat the Ospreys in Limerick, while Harlequins host Leinster at the Twickenham Stoop.

The Ospreys will head to Ireland without injured centre Gavin Henson, and full-back Lee Byrne is battling to overcome a foot tendon injury.

But Ospreys head coach Sean Holley said: "We have got the incentive of a home semi-final in the Millennium Stadium and the dream of making the final."

And Quins are also on the scent of their first semi-final appearance, with rugby director Dean Richards predicting a "battle royal" against Leinster.

"We've played some quality rugby of late. We are on form, with only one defeat in our last 10 games," said Richards.

"But we aren't going to get carried away with the occasion on Sunday - it's just another game for us."
