A "relaxed" Mark McCall insisted Saracens have gone about business as usual this week, in reaffirming the club's belief there is no case to answer over suggestions of a Premiership salary cap breach.

A national newspaper report this week revealed Saracens owner Nigel Wray has business arrangements with stars Owen Farrell, Richard Wigglesworth and Billy and Mako Vunipola.

Saracens issued a statement insisting all those business affairs were a matter of public record and known to governing body Premiership Rugby.

And now rugby director Mark McCall has backed that stance, insisting the Allianz Park men have been unfazed by new salary cap questions.

Asked if the club harboured any frustrations over the issue, McCall said: "Not really, to be honest, because I'm pretty relaxed about it all.

"We've got an important week this week, we've had a great win at the weekend, it's been an encouraging international window for us, our best international window in a number of years.

"This group of young players has done tremendously well, so there's a good feeling around the training ground at the moment.

"To be honest it's just been a normal week, very much training as normal."

Saracens remain confident Premiership Rugby will opt not to launch an investigation into the issues raised this week.

Premiership clubs current operate under a £7million salary cap, but each outfit can make two marquee signings whose wages are excluded from that figure.

Homegrown players and England stars generate extra credits for each club, that can bolster that basic £7million cap, as incentive to foster local talent.

"What we can say is how proud we are of how many players have come into our senior squad from our academy," said McCall.

"We've got a very high percentage of our senior squad that's come from our academy, and that's been the case over a 10-year period.

"A lot of them will be playing for us this Friday night against Bath. A lot will be playing for England against Italy this weekend.

"And I think that's something the club should be applauded for."

Saracens' statement on Monday night underlined the club's confidence that their actions are all above board.

"Firstly, we would like to reiterate that the club readily complies with Premiership Rugby salary regulations and information relating to remuneration is declared to the salary cap manager," the statement read.

"Although co-investment partnerships between owners and players are not a pre-requisite of the salary regulations, we disclose these transactions to Premiership Rugby and will continue to do so.

"Currently, 57 per cent of the men's squad is comprised of home-grown talent - the highest in the Premiership.

"These players not only produce results on the pitch, they help entitle the club to £1.2m in credits above the baseline salary cap from the RFU and Premiership Rugby.

"This is a direct result of our significant investment in the Saracens Academy which nurtures and develops Saracens and England players of the future."
