Wilson scored in the 3-0 rout.
And he declared: "I think being out for so long I wanted a run of games and recently, credit to the manager who has given me that opportunity and I've been playing games.
"We've been working hard on this formation and today we've put everything right and come up with a fantastic performance tonight.
"We knew Chelsea had weaknesses with their back line so we targeted one side.
"Everybody to a man put in a good shift tonight.
"We're unbeaten in six and want to carry that on."
