Jersey's defence has been hailed by fly-half Ross Broadfoot after their 24-16 win in their top-of-the-table clash at Ealing in National One.
Jersey were down to 14 men for much of the final part of the game after prop Ben Evans was sin-binned, but Ealing failed to score despite the advantage.
"It was a real testament to our work ethic," Broadfoot told BBC Radio Jersey.
"Our defence at times was really, really strong and that helped us out."
"It was a real case of everyone digging in and making up for the extra man," the former Richmond, London Irish and Leicester youngster said.
"There were a couple of times when they were down towards our 22 and we turned them over and those are the moments that win you the big games."
Jersey lost full-back Michael Le Bourgeois and centre Dai Bishop early on with injuries, with flanker Guy Thompson having to move to the backs.
"For Guy Thompson from to go from the back row and go into the centre and defend as well as he did I thought was terrific," said director of rugby Ben Harvey.
"We've got a strong squad and the 20 boys made an impact off the bench. Ealing are a very strong side and you're going to need 20 people to beat the league leaders on their own patch and everyone contributed and everyone stood up," Harvey added.
