Gavin Henson will need to prove himself worthy of a place in the Cardiff Blues team, according to coach Gareth Baber.
Henson, 29, has signed for the Blues until the end of the season as he launches his latest attempt to resurrect his injury-hit career.
The Wales centre will face the media for the first time since joining the region on Thursday.
"His job is to come to Cardiff Blues, get his head down and work," said Baber, in charge on a short-term basis.
"Obviously the conversations we've had have assured us that that is going to happen.
"When that happens hopefully he's put in a position where he can push himself into the team.
"But there's a lot of quality in our squad, there's a lot of quality in the boys that are playing on Friday [against Connacht] and Gavin's got to do his utmost to get himself in there and prove his worth in the Blues set up."
Henson was included in Wales' provisional World Cup squad and made his first international appearance in two years against the Barbarians in June following protracted injury problems.
He started in Wales' 19-9 victory over England at the Millennium Stadium in August, but his World Cup hopes were shattered when he dislocated his wrist during the match.
The Blues expect him to train with the squad for the first time on Monday, but have not set a date for his first appearance.
"Obviously he's got a wrist injury to get over," added Baber. "Jamie Roberts was in a similar position last year and it took him a while to get over that.
"So I'm going to reserve judgement on that and see when he gets back. We don't want to push him too quickly."
Henson is thought to have been recruited primarily as a fly-half, although he has won the majority of his 33 Wales caps at inside centre.
Dafydd Hewitt is one player who could lose out as a result of Henson's arrival, but he says the whole region can only benefit from having a proven international in their midst.
"He might relieve a bit of pressure off the team and I think it can only help to have someone of that standing in the side," said Hewitt.
"He's a very skilful player and I don't think he can be matched when he's on form so let's hope he brings that with him."
