Cardiff Blues are set for a major boost as many of their Wales internationals will return to their side for Saturday's clash with Ulster.
The region had 11 players involved in the preparations for November's Test matches but almost all of them are now available for selection.
And it appears stars such as Gethin Jenkins and Sam Warburton are already making a difference at training ahead of the home fixture.
"It is good to have them back, the experience they bring and they are a big part of our leadership group," he told Cardiff Blues' website.
"It's case by case, most guys have come back in with a clean bill of health. It's only Gethin who has played three out of the four games so he will be managed in the best way for him and the others case by case.
"Sam had a stinger for Wales and an injury like that needs to go through protocols through the week and he's passed the first two days. At the moment he seems in a lot better a place and we'll see how it pans out."
After losing to Connacht last week, Wilson is looking for a response from his side at the Arms Park, with the Christmas period approaching.
"We beat Ulster at home last season in quite an exciting game and I envisage something similar on Saturday evening," he added.
"The top of the league have seven wins and we have five so it's very tight but bonus-points are where the difference lies. We're sat in seventh, we've had five wins and the important thing is we've improved our home record.
"We've gone to Treviso, Zebre and Munster and won but picked up a couple of poor results, especially a home derby against the Scarlets in difficult circumstances.
"We're disappointed we didn't pick up anything in Connacht, we certainly created enough opportunity and dropped the ball twice over the line which could have won the game. But one thing we improved on dramatically away to Connacht was our defence. We've spent a lot of time on it in the last couple of weeks and we defended extremely well. If we can see that at home and add to our attacking game on that surface it should be an exciting game."
