The Latics managed a late equaliser to rescue a point.
"We should have had the three points. We came here with the intention to win the game and did everything we could to do so," Schneiderlin said.
"We are disappointed that we have conceded two goals from corners, because from open play you couldn't see how they could score.
"In the last minute to concede a goal like that is disappointing.
"Still, we keep them three points behind us and we are going to try to make that a bigger gap over the next few games."
