Manchester City manager Roberto Mancini was "disappointed" with his side's 1-1 draw with Arsenal at the Etihad Stadium on Sunday.
A late goal from Laurent Koscielny saw the Gunners deny the Citizens their third Premier League win of the season, leaving the Italian lamenting what could have been.
"I'm disappointed because we were 1-0 up and we conceded a goal from a corner," Mancini told Sky Sports News.
"After that we had four or five chances to score a second goal but we didn't close the game. We need to pay more attention.
"It was strange, with just eight minutes to go our concentration should be 100%."
Mancini added that his players played "too deep" in the final 10 minutes of the game.
"We had the game under control," he said. "It was just the last 10 minutes.
"I'm not sure why. We were too deep. We had chances to score. It's difficult as we now have two points less."
City are currently seventh in the Premier League table with nine points from five matches, four points behind leaders Chelsea.
