The things SE is saying now ties in to what happened, so for me makes it more believable.
“lack of security”
We know he wasn’t offered a contract, rather a verbal agreement. Probably one of the most ridiculous and embarrassing things I’ve heard our great club do, just above offering Tony Clubb a 2yr extension.
“Coaching staff choices weren’t approached”
Wigan have kept the same back room staff for Lam as with Wane (minus Bitcon) for the second season running. That either means Lam didn’t want his own staff, plausible as he was only supposed to be here for one season, or he was never given the choice - plausible again as there has been no movement. IL likes the assistant to Head Coach route, as proven with Wane and probably why John Winder is still there. Honestly I can believe IL didn’t want SE’s coaching staff as they’d cost a fortune as opposed to the much cheaper option he has now.
“Williams sold behind my back”
Nothing really to back that up but given IL has been adventurous with the truth in the past it’s hard to not be tempted in by the notion he hasn’t been truthful with SE.
There’s 3 sides to every story; version A, version B and the truth.
