Catalans coach Steve McNamara said his side are nowhere near where they need to be if they want to challenge for silverware this year.
Current Challenge Cup holders Catalans sit seventh in the Super League table, winning just four out of their opening eight games.
Speaking after their loss at Wigan, McNamara said: “We were completely beaten in every department by a team who were hungry and energetic, we were exactly the opposite to Wigan.
“We are not good enough to underestimate any team at this stage. I thought we prepared really well for the game but we came out and put in a disgraceful performance to be honest.
“I thought we were as ready as we’ve been to play a game this year. We were in the contest until just after half-time but once the gap opened for Wigan then the floodgates opened. Our performance was just not good enough.
“We got beat in every department of the game. Our game management was awful from the beginning, which set the tone for the game. We didn’t put Wigan under any pressure whatsoever and we let Wigan’s back five do whatever they wanted against us. There is a quite clearly a problem with our attitude, we weren’t good enough.”
The Dragons have been nilled on two occasions this season, with their first being a 46-0 thumping at home Salford Red Devils.
McNamara revealed Catalans need to change their mentality if they are to compete for trophies this year.
He added: “The last [heavy] loss was at home against Salford so we’ve had two big defeats, one at home and one away.
“We are kidding ourselves if we think we are anywhere near where we need to be right now because we’re not.
“I keep feeling at times that we are building towards where we need to be, but it’s clear that we’re mentally not at the stage yet to be able to compete right at the top.”
