And while the Welsh full-back - who won man of the series for the successful Lions last summer - is excited about the prospect of linking up with his new teammates, he admits that missing out on the chance to say farewell to
the Blues has hit him hard.
"I would have loved to put that jersey on for one last time," he said.
"[They're] a fantastic group of boys and I've loved my time here. I'll miss the squad massively and the fans as well who have been fantastic since I arrived here.
"When I had the injury I realised then I'd played my last game for the Blues for the next three years at least and I was gutted."
