Michael Dobson admits Hull KR will have to improve significantly when they take on local rivals Hull FC next weekend despite their battling 26-22 win over Castleford Tigers.
Former Canberra Raiders half-back Dobson has been struggling with a hamstring injury and handed the kicking duties over to Travis Burns, who scored his first Super League try in Sunday's victory.
Despite his nagging injury, Dobson still played a key role, setting up the home side's second try for Kris Welham in difficult conditions.
But he conceded there was still plenty for his inconsistent team to work on before their derby clash.
"It was pretty tough and the wind was very strong and very cold," Dobson said. "We dug in there, it wasn't our best performance by any means but we got the win.
"It was a bit frantic and we will have to be a lot better next week when we play Hull.
"We let them down in our half too easily but if we can cut those errors out then we will be better next week."
On Saturday, London Broncos saw their good work go to waste when they conceded a last-minute try against Hull FC, Richard Horne's effort converted by Danny Tickle in an 18-18 draw.
Broncos coach Tony Rea, who played more than 100 games for the North Sydney Bears, admitted it had been frustrating to throw away a point late on, but he took some comfort from the imminent return of Craig Gower.
"It's hard to say we're happy with a point," he said. "It doesn't feel like a win, having been in front for a large part of the game.
"Having said that, we left nothing out there and the spirit of the team along with the enthusiasm and the effort was everything you want to see.
"I'm only disappointed because Hull scored a last-minute try, and it's then that you start feeling like we should have won.
"It was a contest from start to finish with both teams fighting all the way.
"We didn't have Craig Gower as he had a groin issue from last week. If he was fit he would have played, but he should be back for our Easter games."
Warrington moved to within a point of leaders Huddersfield on Friday, hammering the league leaders 28-2 in arctic conditions.
Brett Hodgson, who played for both Wests and Paramatta in the NRL, was instrumental for the Wolves, scoring a try and kicking six goals and coach Tony Smith admitted the veteran had shown all his experience.
"That was tough - a good old traditional winter rugby league game," Smith said.
"The players really did put their bodies on the line and handled it pretty well. I think the pitch and conditions brought everybody back to Hodgson's pace.
"He read the game well. He's a good pro and there are things that he does very well that he did for us at the right times."
