"It's got nothing to do with what we're doing now and had no bearing on the result on the weekend. We've made some improvements in that area [club culture] but we need to obviously keep getting better."
When pressed on how much improvement is still required, McFadden reiterated that the levels of discipline and professionalism at the club had been raised, but conceded the Warriors still have some way to go before they find consistency in their performance and recruiting the right players to help them achieve success.
"On that side of things we're a lot better," he said.
"It's more to do with the way we play, the consistency we play with, and we're still working on our squad management. We need reliable people. We need class players that can help us get to where we want to."
He continued by detailing areas his players need to be more accountable in and the things they can do to further assist and improve their performances each week.
"It's the fundamental sides of the game. Off the field it's the way they prepare, the way they eat, sleep, hydrate and recover. On the park it's the standards that we uphold and that we drive at training."
Back-rower Ryan Hoffman said he had noticed a difference in club culture after arriving at the Warriors this season after 12 years at the ultra-professional Melbourne Storm.
"I came from a club that had certain standards and the standards here were a bit different," he said.
"Melbourne has had the same coaching staff, system, ethos and philosophy for the 12 years I was there so it was very easy to have that consistency with professionalism.
"Coming here to the Warriors, there's been a change, especially over the last 12 months. We're working hard on that professionalism and it's getting better.
"Previously there's been a few people that liked the idea of being a professional player but not exactly what it takes to actually be one.
"Those are areas we are improving as a club and that comes down to us as a team having those non-negotiables and slowly but surely players are starting to buy in."
