Sunderland boss Martin O'Neill feels victory over Manchester City was their best result of the season.
Adam Johnson proved the matchwinner against his old club.
Asked if the performance was Sunderland's best of the season, O'Neill said: "Considering the opposition, I would have to say yes.
"We gained a bit of confidence form winning against Southampton and took that into the game, but we knew there would be times when we would have to play without the ball and we would have to defend strongly, and we did both of those very well.
"And yet we were able to carve out some great chances in the game."
