Wigan lost some influential players over the winter in George Carmont, Brett Finch, Thomas Leuluai, Jeff Lima and Gareth Hock but Wane felt his players sent a good message to people writing them off.
He said: "I heard all those comments about us but I know we can play. That wasn't a complete performance - too many penalties and a little loose in contact. Once we fix that up we will be okay this year. It blew the cobwebs out. We had a few players a bit rusty but I'm happy with the performance."
He added: "I knew it was going to be a test in the early period and all credit to them for sticking at it, but I thought we were quite good today."
Wane was also keen to make sure the praise was shared around even though it was inevitable Super League poster boy Sam Tomkins, who scored three tries, would command most of the attention.
He said: "The front rowers were outstanding today. Sam is a great player and the work the middles (forwards) did was outstanding."
Salford coach Phil Veivers was not sparing in his criticism of his side despite accepting his the club's difficult winter had left his squad well short of being competitive. The Reds were close to going out of business before Dr Marwan Koukash's takeover was finalised this week.
Veivers said: "We didn't help ourselves throughout the game. In the first half we conceded two really poor tries. We came out in the second half and didn't get a lot of the ball. We were very poor with our skill levels, our execution of the skill and some decisions made defensively were poor.
"But I have always said we are probably three months behind every other club because we haven't had a pre-season. In that side were three bodies who haven't really trained with us.
"There might be some mitigating circumstances but at the end of the day you go on the field and you are able to make a tackle and pass a ball. That let us down tonight."
