Sale director of rugby Philippe Saint Andre told the club website: "The Challenge Vaquerin will be very tough for us but will help the players in their preparation for the new season.

“The double header on Friday 22nd August will give me the opportunity to look at all my players in action on the same evening. It will also give us the opportunity to learn and put into practice the Experimental Law Variations. Places are up for grabs for the new season and it should be a great night for the supporters too."
