Oldham coach Scott Naylor says the pressure is on Hull KR when the two sides meet in the Challenge Cup this weekend.
Back in 2016, as a Championship club, Oldham caused an upset by defeating the Robins 36-22 at Craven Park to reach the last 16 of the competition.
There are still a sprinkling of players in both sides from that day, though James Webster has since been displaced as coach at Hull KR by Tim Sheens.
Naylor said: “Rovers won’t take us lightly. They won’t want THAT to happen again so it’s going to be extremely tough.
“All the pressure is on them, though. There’s none on us, other than what we put on ourselves.
“They’re a Super League club and rightly so. It’s good to have two Super League teams in Hull.
“They’re a different team to the one we played two years ago so we know it will be very tough, but what’s the point of playing rugby if you don’t want to challenge yourself?”
Last season, Hull KR caused an upset of their own as they beat then Super League side Leigh 23-10 at this stage, before going down 24-14 at Salford.
Oldham, who were relegated from the Championship at the end of last season, have won three and lost three of their six League One games this term.
Hull KR have managed three wins in their 11 games since returning to Super League.
