Veteran Australian Alan Gaffney has been named as Northampton Saints' technical coaching consultant on a deal until the end of the season.
Premiership strugglers Saints sacked director of rugby Jim Mallinder this month after 10 years at the club.
Gaffney, 71, has been chosen to oversee the team until the end of the term and he is no stranger to British and Irish rugby, having spent two years as director of rugby at Saracens, as well as coaching spells with Munster, Leinster and Ireland.
"I am really excited about the challenge ahead," Gaffney told the club's official website.
"Any coach would jump at the chance to work with the calibre of players Saints have.
"The squad have shown what they're capable of earlier in the season but, for whatever reason, they have not been able to perform at that level consistently."
Gaffney will work with acting head coach Alan Dickens, forwards coach Dorian West, defence coach Phil Dowson and assistant coach Mark Hopley at Northampton.
