Gareth Thomas is hugely experienced in rugby union
Cardiff Blues director of rugby Dai Young says that Gareth Thomas' cross-code switch has his blessing.
Ex-Wales and British and Irish Lions captain Thomas, 35, was officially unveiled by rugby league side Crusaders on Friday as their newest player.
Thomas' Blues contract ran until May but the Welsh region has released him early so he can play in Super League.
"I'm pleased for Gareth because he always wants that next big challenge," Young said.
"He's done everything in rugby union and his consistency over the years has been amazing.
"It'll be a big challenge for him, it's difficult, but it's a bit easier for a back to change than a forward and he's got all the attributes to make a success of it, there are no doubts in my mind."
Young knows the lure of the 13-man game, having changed codes himself as a player when the former prop joined Leeds in 1990, before being snapped up the following season by Salford.
"If I wanted to be a selfish coach I could have kept until the end of his contract [in May], but Gareth asked to be released to take up the challenge he wanted and I think we owed him that," Young added.
"His profile will be a big benefit to the Crusaders, he can be a big marketing tool, but his mind is on the rugby.
"He's a bit of a one-off larger-than-life character and I'm sure that he'll enjoy the next challenge."
Thomas is hugely experienced in rugby union, having played for Bridgend, Celtic Warriors, Toulouse and the Blues, mostly at wing or centre.
He also captained Wales to their first Grand Slam in 27 years in 2005 - he is the only player to have reached 100 Wales caps - then took over the Lions leadership in New Zealand during the same year.
Although he will have to learn a new game, Blues team-mate Tom Shanklin is sure that Thomas will thrive in Super League.
"I'm thrilled for him, he's done everything there is to do in union and this is a new challenge for him. I'll definitely be watching his games," Shanklin said.
"He does love a challenge and I'm sure he'll shine."
