Wigan boss Shaun Wane admitted the Warriors got what they deserved after blowing a 20-0 lead at home to Wakefield on Monday.
Bill Tupou’s quickfire hat-trick sparked Trinity’s comeback as the Yorkshire side went on to claim a 42-30 victory and boost their hopes of a top-four finish.
“We just fell apart and missed too many one-on-ones,” said Wane. “It was a great start but we gave a few penalties away and just didn’t make those one-on-one tackles. We made some poor defensive errors and put ourselves under pressure.
“They were the best team. We were a bit out of juice. They are a big team, we came into it a bit lethargic and you try and manage their big bodies.
“Wigan teams should never be giving up a 20-0 lead, no matter what. There is no excuses from us, we were beaten by the better team and I’m disappointed.
“We defended far better at St Helens but couldn’t back it up today. We’ve shipped too many points recently.
“I’ve got belief in the players and they’ve got belief in themselves, but we came up against a big physical team today and we showed a bit of softness in defence and that’s disappointing.”
