Callum McManaman was the match-winner, sealing the points 10 minutes from time after superb play by the electric Shaun Maloney.
"Today, you'll have a hard job finding a negative in our performance," the Spaniard said.
"It's an incredible story about Wigan Athletic. It's about winning a football game; it's about three goals from open play away from home; it's about coming back from behind; it's about being able to keep the ball and be aware in everything you do.
"The mentality was magnificent today. Our performance was full of character and I couldn't be prouder of the team."
