Wales defence coach Shaun Edwards insists Gavin Henson is in great condition ahead of the autumn internationals.
Henson looks set to start against South Africa on Saturday despite having only made four appearances for the Ospreys this season.
A serious ankle injury, followed by a two-match ban for a breach of internal discipline meant that Henson is lacking match practice.
However Edwards has no doubt that Henson will be in perfect shape to tackle the Springboks.
Edwards said: "If you look historically at the Welsh team, there is no doubt Gavin Henson has had a good impact when he has played.
"The team has won a lot more than they have lost. We are more than happy to have Gavin back.
"As regards is he fit enough? He looks in great condition, his strength is superb in the gym, and you can only play yourself back into match fitness. The more matches he gets under his belt, the better.
"I hope he has a similar impact to what he had in the last Six Nations. He has been solid in defence for us, and he has been a real threat with ball in hand.
"He is a guy who can make the half-break, and he also has a very big boot on him, when needed."
Henson is likely to partner Cardiff's Jamie Roberts in the midfield, with Edwards insisting the 21-year-old is a natural centre.
Roberts has won three caps for Wales, but has so far played at full-back, on the wing and in the centres.
And it is in that latter position Edwards believes Roberts will excel.
Edwards said: "From the first moment I set my eyes on Jamie when I joined the Welsh set up I mentioned to Warren (Gatland) could we get him to play at centre a little bit more.
"To me, if you put Jamie's stats into a computer he would come out, potentially, as a top-class centre.
"I've watched him with the Blues the last few games and I think Jamie has excelled."
