Australia utility back Kurtley Beale has been named in the Wasps team for Sunday's Champions Cup tie against Connacht.
Beale, capped 60 times by the Wallabies, has been recovering from a serious knee injury which delayed his debut following a lucrative switch to England from the Waratahs in a deal said to be worth around £700,000 per season.
It has been a long road back to fitness for the 27-year-old from the potentially season-ending patella tendon problem.
Wasps director of rugby Dai Young is, though, confident Beale can make the anticipated impact in both the domestic Aviva Premiership and European campaigns.
"I have been really impressed with Kurtley's work ethic since he arrived. He's worked his socks off to get back and he has fitted in brilliantly with the squad," Young said.
"We all know how talented a player he is, but he's also very humble and keen to develop further, which makes him a pleasure to work with.
"It was important to wait until he was feeling confident in his knee and his fitness, and it's great he's in that place now after being back in training with the squad for three weeks.
"It will naturally take him a bit of time to get up to speed with our patterns and to return to match-sharpness after a while out, so we'll be patient on that front.
"But he is a world-class talent who has looked hugely skilful in training and we are all excited to have him back and ready to play for Wasps."
Wasps will also be boosted by the return of England internationals Joe Launchbury and Nathan Hughes while Christian Wade returns from a foot injury for the Champions Cup Pool 2 tie at the Ricoh Arena , which is the first of back-to-back matches against Connacht.
