The Robins travelled to Wigan for a Super League contest recently where they were destroyed 60-0.
Several players have returned from injury since then, however, and it will be a different Rovers pack, in particular, which will run out at the DW Stadium on Friday.
“We’re going to need a good defensive attitude to beat them, similar to the one we had against Wakefield last week,” Chester told his club’s official website.
“We know what Wigan can do, they’re a very good rugby league side, and defensively we’ve got to be a hell of a lot better than we were last time, which I’m confident we will be.
“We’ve done a few things differently at training this week and we want to try to shock them a little bit. We’re thinking outside the box and we’ve trained really well but it’s the cup and anything can happen.
“It’s an away game for both teams and we’re going there full of confidence.
“We’re confident we can score points if we get an even share of the ball, so we have to be a lot better at getting through our sets and finishing them with a good kick.”
