Roberto Mancini's men struggled to get going in the game and were lucky not to find themselves behind at the end of the first period after allowing Wigan a slew of chances.
Although Manchester City turned in an improved second-half performance, the defending champions only took the lead 21 minutes from time via Mario Balotelli, who was making his first start in six games. Substitute James Milner doubled City's advantage minutes later via a stunning long-range strike.
Speaking to the club's official website, Barry blamed the team's lacklustre first-half performance on the DW Stadium pitch.
"It was a professional job, the first-half was so tough and the pitch was so hard-going and there were a lot of stray passes but we ground it out in the second half," he stated.
The former Aston Villa man also praised Wigan manager Roberto Martinez's tactical acumen, as he believed the Spaniard knew exactly how to counter the defending champions.
"We have to give Wigan credit, they play with a different formation than we’re used to playing against, with five at the back which becomes a three and in the second half we stepped it up and the manager changed it about a bit," Barry remarked.
"You see a lot of good teams come here and slip up, so we’re delighted to come out with a huge result."
