Adrian Lam is struggling to explain Wigan Warriors poor start to the season but feels the World Club Challenge defeat could be a factor.

Wigan boss Adrian Lam says he is a “bit rattled” by his side’s poor start to the season after suffering their fourth Betfred Super League defeat of the season on Friday.

The reigning champions are struggling to adapt to life after Shaun Wane and Sam Tomkins, winning only once in 2019 in a run that included losing the World Club Challenge to Sydney Roosters.

Lam believes the emotions of that game are still hindering his side and they were again off the pace on Friday as Huddersfield won 14-6 at the DW Stadium.

Morgan Escare scored Wigan’s only try, with Kruise Leeming and Joe Wardle crossing for the Giants while Lee Gaskell added three goals.

The Warriors would be sat bottom of the table were it not for their two-point penalty for salary cap breaches being lifted and the uncertainty surrounding the club has been added to by doubts over the planned arrival of Shaun Edwards.

Lam was installed as a stop-gap for the season and admits he is unsure how they are going to find a solution for this current slump.

“I’m a bit rattled really,” he said. “They looked like a shell of their former selves. We are training well, but we just can’t put a finger on it. I’m just a bit lost at the moment.

“They look like they don’t have confidence. We are making basic errors, like a simple pass and catch which is uncharacteristic of them. Three simple drop balls with no pressure. That’s an attitude problem.

“Maybe there is some attitude that they think we deserve to win without having the effort that comes with it, I don’t know. They are emotionally drained from the (Sydney) Roosters game. It’s not good.”

Wigan are 9/1 to retain their Betfred Super League title, while their next opponents Warrington share the market lead at 9/4, alongside St Helens.
