Toulouse coach Yannick Bru is struggling to find a weakness in Munster's arsenal heading into tomorrow's Heineken Cup final in Cardiff.

Declan Kidney's men emerged from a tough group that included Clermont-Auvergne, Llanelli Scarlets and holders Wasps before beating Gloucester and Saracens away in the knockout stages to reach the final.

The recruitment for this season of Rua Tipoki and Doug Howlett has given them some added flair in the backs that dovetails nicely with their renowned strength in the pack.

Bru admits his Toulouse side face an "immense challenge" to prevent Munster repeating their exploits of two years ago, when they beat Biarritz in the 2006 final at the Millennium Stadium to claim the Heineken Cup for the first time.

"We have a lot of respect for them," said the former France hooker.

"They are a team with a lot of quality in all set-piece phases with the ball, and have a presence in the line-out, the scrum and in the rucks.

"They are opportunistic from lost balls, possess great experience and apply constant pressure on their opponents.

"They now have speed out wide this year. They have signed two centres of great talent (Tipoki and Lifeimi Mafi) and there is Doug Howlett on the wing who remains a permanent danger.

"They got out of a high-quality group, and went and won at Gloucester and Saracens. So hats off to them for the run they have had.

"An immense challenge awaits us."

Toulouse are enjoying a great post-World Cup season themselves, as they are also flying high in their domestic Top 14 championship.

But they are paying a price for their success, with a congested fixture list and injuries to key personnel - such as France winger Vincent Clerc - hampering them over the past few weeks.

While Munster have been able to rest many of their key players in recent Magners League matches as they fine-tune their preparations for the Cardiff final, Toulouse have not been so fortunate.

Bru is at pains to point out Munster will be in far better shape than his team heading into this weekend's showpiece.

"In the Celtic League, Munster play very few of their first-choice team - they give a lot of recovery time to their players," he said.

"They work like their national team, and prepare for the Heineken Cup like the Ireland team prepare for their international matches.

"We feel they are helped a little more by their domestic calendar.

"That (the calendar) is the biggest bugbear of all the French teams who are involved in the final rounds of both competitions.

"In a post-World Cup season, it is a real marathon to try to battle on two fronts.

"Since our quarter-final win over Cardiff, you must take into account the run of matches we have had and the injuries to have befallen us.

"It has been difficult."

Les Bleus internationals Clerc (knee ligaments) and Clement Poitrenaud (ankle) will definitely be missing tomorrow while New Zealand scrum-half Byron Kelleher is a doubt with a sore thigh.

Tonga number eight Finau Maka has not travelled for personal reasons.
