The 20-year-old, who scored nine tries in 27 appearances during the campaign just gone, signed a two-year deal with the club this week from Keighley Cougars.
Kilshaw – who previously gave the full-back his professional debut – feels Sayner can thrive at Oldham under his leadership.
“He’s got a big future in the game and, incredibly, he doesn’t turn 21 until June,” he said.
“Since I came to Oldham, I’ve been really keen to get him here. I think he’s someone our supporters are going to be really excited about.
“He has speed and agility to burn, he’s tough, and he has a real hunger to improve.
“I feel our environment, alongside the quality and experience we have within the squad, will really suit him.
“I’m confident he can thrive here and light up the Championship next season.”
Having come through the Bradford Bulls system, Sayner earned a move to Keighley after impressing on a trial during pre-season ahead of the 2025 campaign.
As well as reuniting with Kilshaw, Sayner will link up with his best friend, Lucas Green, who has also joined the Roughyeds on a two-year contract.
After putting pen to paper, Sayner expressed his delight with the move.
“As soon as I heard that Oldham were interested, I wanted to sign,” he explained.
“It’s a big club and Oldham have done well this year, so I am absolutely buzzing about the move.
“I’m quite a running threat, quite agile, so I can move pretty quick and I like to think I bring plenty of energy as well.”
The chance to reunite with his former head coach made the decision an easy one.
“As soon as I heard that Oldham were interested, I wanted to sign,” Connor added.
“Ever since giving me my debut, it seems like he trusts me.
“We get on quite well also, and it does play a big part in you getting along with your head coach, so it has brought out a lot of confidence in me.”
