Wasps have appointed Dai Young as their new director of rugby.
Young joins from Welsh region Cardiff Blues and replaces Tony Hanks, who presided over Wasps' decline as a force in the Aviva Premiership.
The 43-year-old former Wales and Lions prop won the Amlin Challenge Cup and EDF Energy Cup and reached the semi-finals of the Heineken during his nine-year reign at the Blues.
"This is an enormous opportunity for me. I loved my time at Cardiff but I'm looking forward to a new experience in a new environment," said Young.
"There is a hugely talented group of players here to work with, and the challenge to help a great club into a position where they are once again challenging for success was too good to turn down."
Young won 51 caps for Wales, was selected for three Lions tours and has led the Barbarians as head coach of the European tours for the past four years.
Wasps chief executive Chris Thomas hopes that he will be able to spark a revival in the club's fortunes.
"We believe Dai is exactly the right person to take the club forward," Thomas said.
"Dai brings a wealth of experience to the club and this is an appointment for the long term.
"We remain an ambitious club and want to be competing at the highest level. Dai is the person to help us achieve these ambitions."
