Saracens boss Mark McCall insists his team having nothing to fear when they take on Toulon in the semi-final of the Heineken Cup at Twickenham on Sunday.

The big-spending French giants boast a star-studded squad of internationals including Jonny Wilkinson, Frederic Michalak and Sebastien Bruno but McCall believes the Men in Black can be more than a match for their opponents.

"What they’ve done well is they’ve recruited not just world class players who have achieved a lot but world class players who have achieved a lot and are still ambitious," said McCall.

"So they do have a really big collective will and a motivation and ambition to do well but has it been challenged?

"We’ll soon see this weekend but one thing I can guarantee is that we’ve got a lot of togetherness and we’ll give them a hell of a run for their money."

Toulon knocked out Leicester Tigers in the quarter-finals and Saracens are now the last English team left in European rugby’s premier competition.

The French side, like Sarries, are fighting on two fronts as they sit second in the French league’s Top 14, one point behind Clermont Auvergne, who play Munster in the Heineken Cup’s other semi.

But McCall believes the fact that many of Toulon’s players have played in the Premiership, against some of Saracens' players, will help remove any intimidation factor.

"They do have a very good team and they do have some really world class players but we think we do too," McCall said.

"And if you go through their team quite a few of them have played in the Premiership and our players have played against these players before so for me that takes some of the mystique away.

"They’re a good team though because as well as having very good players they’re very well organised, very structured very regulated in certain things they do.

"It seems to me that in the Top 14 some of those things are never challenged and we have to challenge some those things they do in the Top 14 week in week out."

Perhaps the game’s most intriguing battle is between England’s iconic World Cup winning fly-half Jonny Wilkinson and this country’s latest number ten Owen Farrell.

Farrell, 12 years Wilkinson’s junior, has been in scintillating form for Saracens this season but Mark McCall believes the key to stopping Toulon’s main talisman will come down to more than a personal battle.

"He’s a great player for them and he’s instrumental to what they do," McCall said.

"But it’s not just about Jonny, it’s about stopping Jonny being on the front foot and you do that by doing other things as well - you get at Jonny by getting at everything ."
