Manchester City goalkeeper Joe Hart has described Sunday's derby defeat to Manchester United as one of the worst days of his career.

City were swept aside at Old Trafford as United all but ended their rivals' slim Premier League title hopes with a 4-2 win.

The result has left the defending champions in fourth place in the table, 12 points adrift of leaders Chelsea.

"That's one of my worst [days] in a Manchester City shirt, definitely," Hart is quoted as saying by The Mirror. "We let ourselves down and we let our supporters down, but there are six games to go now and they are so big for us.

"Not many teams have put us to the sword like that. United know what they're doing, they took their chances. I didn't have an overly busy day, but United took their chances. I'm hurting from this defeat, there's a lot of emotion running through me."

City have the chance to get back to winning ways on April 19 when they host West Ham United in the league.
