Swansea defender Ashley Williams believes the club has taken its "eyes off the ball" as the Premier League draws to is final conclusion for the season.
However, the Welsh international denies the club's Capital One Cup triumph is the root of the recent malaise.
Swansea have been suffering through an indifferent run of form recently, two losses only offset by a trio of draws - a remarkable difference to the style of play that took the club to a victorious assault on Wembley.
But despite admitting he is as disappointed with the club's recent run of results as anybody, Williams has refuted the club is suffering from a silverware hangover.
"It's not good enough," he said. "If you take away the Arsenal and the Tottenham games, we should have done a lot better in each of the other matches.
"I think, for whatever reason, we took our eye off the ball. But I also thought against Manchester City we performed well and were back on our game.
"It's not been enjoyable not winning a game for so many weeks, but a draw against the ex-champions isn't a bad result.
"It's easy to say we thought the season was over after Wembley, but I didn't think like that and I don't believe any of the other players did.
"It may look that way from the outside, but we've done well in games. There have just been critical periods when the opposition have scored, while we've missed chances and that has cost us.
"We put pressure on ourselves, we said the City game was an important match and we wanted to perform well. I think we did that."
However, Williams said The Swans produced one of their better games in recent weeks against City, especially facing the enormous task of keeping the reigning champions scoreless for 90 minutes.
"It's the best we have played in recent weeks," he said. "The second half was tough, we got tired and I think the front players were working so hard defensively when Manchester City got on the ball it was hard for them to actually keep it from us.
"City were always going to have chances, but the pleasing thing for me at the back was the way we stuck together and helped each other out."
