“He’s ready to play. Not having played probably since March with Toronto, it’s been a span of time for him and it’s important for him to get back out there and get the match fitness.
“You can run around, sit on a bike and do whatever you like for as much as you like but getting that match fitness is important.”
Williams regaining his match fitness will prove critical as the Tricolours edge closer to their run at a third consecutive premiership.
But Robinson also wants to see Williams integrated back into the Roosters’ system, which has developed in the six years since he last pulled on the red, white and blue.
“There’s the physical needs – getting him physically ready to play – and then there’s the other part, which is understanding the system,” Robinson said.
“Which he did. But there’s more depth to our system now and he’s a learned guy. He studies hard.
“He would do as much video of anybody that I’ve seen. He writes down as many notes as he needs to write down and that’s how he gets his preparation as well.”
Robinson can grow tired of answering questions away from the game ahead of his club but understands the hype surrounding Williams’ return.
“I’m really excited to have him back and I knew what having him back would do. So I’m definitely not sick of it,” Robinson replied when asked whether he was tired of talking about Williams.
“I’m really excited and I think it’s great for the game and great for fans to watch.
“I’ve had a lot of people mention the excitement and externally, that is the biggest talking point.
“Internally, it’s how do we want to play?
“We want to get better, every game. And that includes this weekend.
“We want to nail the way we want to play on Saturday night and we want to honour Josh Morris playing in 300 games.
“That’s the internal focus for us.
“We’re really excited about having Sonny get started with us and the external focus will be large on that, which is great and really important as a Rooster and a fan of rugby league.”
Morris will play his 300th game, Luke Keary has been named at No. 6 in his return from a rib injury and both Angus Crichton and Mitchell Aubusson are “close” to returns, according to Robinson.
