Saints legend Sean Long has been appointed Keiron Cunningham’s assistant coach.
The 38-year-old has agreed a two-year deal to return to his spiritual home.
He will take on assistant coaching duties alongside Jamahl Lolesi.
Named in Saints’ Greatest Ever 17, Long enjoyed a glittering 13-season career in the red vee.
He won two World Club Challenges, four Grand Finals and five Challenge Cups as well as being named Lance Todd winner three times.
He left in 2009 to join Hull FC and then coached at Wigan before assisting at Salford and Samoa.
Cunningham said: “I am really happy that Sean has agreed to join my team. He is a legend at this club and will bring years of experience not only as a world class player but also as a first rate coach.
“He commands respect amongst the playing group and will complement our backroom team perfectly.”
Long scored 2,625 points for Saints in a career that spanned more than 330 games.
“I am delighted to be back at a club I love so much,” he said. “Saints are one of the greatest rugby league clubs in the world and to be part of the backroom team here was too good an opportunity to turn down. It was my chance to come home.
“The opportunity to work with Keiron Cunningham - a teammate and friend who was and still is a legend at Saints - and the great squad the club has is very exciting.
“I am keen to develop my coaching career and working alongside Keiron, Jamahl Lolesi and Paul Wellens, as well as the rest of the squad, will enable me to do that.
“I’d like to thank Salford Red Devils for their support and the opportunity to continue my coaching career there. I wish all the staff and the players the best for the future.
“I’d also like to thank Eamonn and the board for the opportunity to come back to the club I played the majority of my career for.”
