HULL KR coach Craig Sandercock has urged his players to improve in almost every area when Warrington arrive tomorrow.
The visit of the Wolves to MS3 Craven Park is Rovers' biggest test of the season so far.
Although they have just one win from four games so far, KR don't need to improve their attack, which is averaging 30.5 points a match.
However, Sandercock still knows there is a lot to work on.
"The focus this week has been on improving all areas of our game," he said. "The players want to work hard and be competitive this weekend.
"Warrington are a class side and they have been the benchmark for the last few years in Super League.
"They have taken their time to build a good side and they are reaping the benefits at this moment in time."
Sandercock was impressed with the way Hull FC contained Warrington's star-studded side last week at the KC Stadium, even though the Wolves eventually found a way to win.
"It's up to us to try and limit their try-scoring opportunities," Sandercock said.
"The key to stopping them from getting on a roll is not to give them too many repeat sets.
"If you have momentum, you roll with it. If you don't have it, you have to hang in, do your best and scramble well, work hard for each other and wait for the tide to turn.
"And when we do have the ball, we have to make the most of it.
"We need to take every opportunity we get."
