Jason Chan believes Hull KR can take advantage of Widnes' loss of form by beating Hull FC to give their play-off hopes a shot in the arm.
The Vikings are just two points clear of the Robins with three matches left to play, but have lost three of their last four games.
That included a deflating Challenge Cup semi-final defeat by Castleford, which has caused Denis Betts' side to stutter on their return to the league and a tricky test against Wigan awaits on Friday.
But having impressed in a 14-14 draw with Wigan, Chan believes Rovers can overhaul Widnes if they play the same way against Hull FC in Friday's clash at the KC.
"We are taking things one game at a time," Chan told the Mail.
"Widnes are catchable and with the squad we have I think we can overtake them.
"We have some very good structures in place and we have to stick to them against Hull, Catalan and Wakefield.
"They are all winnable games for us between now and the end of the season."
Chan will experience his first Hull derby on Friday when Rovers make the short trip from east to west for the third and final one of the season.
Rovers hold the upper hand with two wins from the previous two competitive meetings and will be chasing an historic first.
No club has completed a clean sweep of derby wins in a Super League season, but Chan is determined to make that happen to send the KR fans home happy.
"I always enjoy night games," said the on-loan Huddersfield forward, who will return to Australia at the end of the campaign.
"Between now and the end of the season I want to play all the remaining games.
"I want to stay injury free and play my part in getting Rovers to the play-offs.
"I'm determined to leave this club on a good note and hopefully I can do that.
"This club is clearly on the rise with very good foundations and a successful under-19s side this season.
"The future looks good."
Brought in midway through the season by coach Chris Chester, the 30-year-old Papua New Guinea native has further strengthened the club's links with his home nation.
He is the fourth Kumul to represent Rovers in the Super League era after Makali Aizue, Stanley Gene and current squad member Neville Costigan and is honoured to be part of that link between club and country.
"When I got the call to come here, Stanley made the transition very easy for me," he added. "There is a good alliance between PNG and Rovers and it helps having Neville in the team too.
"PNG is rugby mad and it's great to have their support. I'll be aiming to do my best for them while I'm here."
