Former Saints performance director Nick Johnston has joined Worcester Warriors.
Johnston spent five years at Northampton before leaving the club in October.
He helped the Saints reach six finals in as many seasons and ensured they were one of the fittest squads in the English top flight.
And he will now take his expertise to Sixways after agreeing to join the Dean Ryan revolution.
“This is a tremendous challenge and I am excited by the vision which this club clearly has,” said Johnston.
“I have known Dean for many years and I am a great admirer of everything he has done in the world of rugby.
“Having left the Saints after several wonderful years at the club I needed a new challenge. This is exactly the challenge I’ve been looking for and I cannot wait to get started.”
Ryan, who has endured a tricky start to his tenure at Warriors, seeing the club fail to win a Premiership game so far this season, is looking forward to working with Johnston.
And the director oif rugby said: “I am absolutely delighted that Nick has agreed to join us. His record in high performance management and the development of the academy programme is second to none and I know this appointment will be a tremendous boost to this club.
“His appointment is further evidence to our ever increasing commitment to the long-term development of Worcester Warriors.”
