Saracens: Premiership champions say they 'readily comply' with salary cap rules
Premiership champions Saracens insist they "readily comply" with the division's salary cap regulations.
A Daily Mail investigation revealed a number of business dealings between owner Nigel Wray and some of the club's biggest earners.
Those dealings have raised questions about whether the club operate within the rules.
Saracens say all transactions are disclosed to the league's salary cap manager.
The club also say they are able to spend above the £7m cap because of the high proportion - almost 60% - of home-grown players in their squad.
Premiership Rugby confirmed it will look into the latest information to determine if Saracens are in breach of regulations.
"Premiership Rugby has a duty to all clubs to deliver the system in a transparent, objective and non-discriminatory manner," added a league spokesperson.
"There have always been rumours and questions about how they afford that high level of player," England and Harlequins scrum-half Danny Care told the Rugby Union Weekly podcast.
"We have had some frustrations in the past and a major reason why [former Quins coach] Conor O'Shea left was he felt it wasn't a level playing field and nothing was being done.
"When it happened a few years ago it got swept under the carpet a little bit.
"Saracens are a brilliant team with great coaches and great players. You would like to think everything is above board."
