The Rhinos face a difficult trip to third-placed Leigh on Thursday.
Arthur’s men are fifth in Super League with seven games of the regular season to play but have lost two of their past three matches.
However, he praised the side’s efforts as they look to secure a play-off place.
“The boys have shown me enough that we are heading in the right direction as a club and that the buy-in is there,” he said.
“We’ve shown a truckload of character and fight in our performances this year. Some games we haven’t managed the best, and our tactical discipline might have suffered here or there.
“In terms of fight and character the team has been full of it every game. Now it’s my job to make sure we’re on top of our game tactically, and that’s a work in progress and something that takes a bit of time as well.”
