Outgoing Cardiff Blues head coach Danny Wilson will join Wasps next season as Dai Young bolsters his coaching team.
Wilson will work primarily with the Aviva Premiership club's forwards and joins Young's backroom staff after two years in the Cardiff hot seat.
Wasps confirmed the appointment Thursday morning as they also announced that Nottingham head coach Ian Costello would supplement the club's coaching staff, with a focus on skills development and exits.
"The opportunity to work with Dai [Young] was one of the big attractions of moving to Wasps," Wilson said. "He is a very experienced director of rugby and I could see the quality of his coaching during his time at Cardiff Blues. His record with Wasps goes before him, having taken the squad from 11th place to the Premiership final during his time at the club.
"They only just lost out on the title last season and you can see what a fantastic squad Dai is building through excellent recruitment and retention of quality players. I'm looking forward to learning from him as a coach next season and to being part of the infrastructure Wasps are creating.
"The ambition of the club is clear to see. They have a talented group of players who play a really exciting style of rugby that attracts big crowds. It will be exciting to be part of. Until then, I will be doing everything I can to help Cardiff Blues achieve our goals for the remainder of this season."
Young added: "We have operated with a smaller coaching team than most clubs for a while now.
"The plan was always to bolster it, as we already have our S&C team, but I have taken my time to make sure I bring in the right people who really add to what we're doing and complement the quality we already have within our coaching department.
"I couldn't find the right fit last season, but I'm pleased to have found people that I believe can really benefit the whole team next season."
