"Cappy's already made gains and he's got two of New Zealand's best players coming to the club next year (Roger Tuivasa-Sheck and Issac Luke) and that's pretty hard to do.
"People have just got to be a bit patient. Although we had big hopes for this year, things change and things happen, and you've just got to roll with it and that's all we're doing at the moment.
"It's just unfortunate that we're not getting those wins to show how hard we're working."
Johnson also scoffed at suggestions the Warriors could not win without him in their line-up and backed fill-in No7 Tui Lolohea to do the job in his absence.
"It's a load of crock really," he said. "It's alright to say that I have an impact on it because being the halfback of the side that's a pretty big role to fill. I think Tui's doing an awesome job but we're completely different players.
"There's been a lot of things go wrong. Just unfortunate things with injuries at the wrong time of year and it puts a lot of pressure on our squad.
"We've got young kids stepping in at the moment that are doing their best and they're playing against full NRL players in the toughest league comp in the world, so it's not just one thing.
"They can win without me and I've lost games playing with the Warriors so it's got nothing to do with that."
Johnson supported comments made by McFadden last weekend that detailed the poor culture and lack of professionalism at the Warriors in years gone by.
He says the difference in the player's attitudes and club culture is vastly improved from what it was when he first emerged on the scene back in 2011.
"I can definitely say, looking back to where it was when I first came in, maybe the first two or three seasons I was at the club to where we are now, it's a complete change.
"It's hard for the outside people to see at times but I definitely know we're heading in the right direction and I'm behind Jim and Cappy 100 percent."
