Sunderland's Kieran Richardson has apologised to the club's fans for their defeat to Norwich on Monday night
Norwich picked up their first win of the season at Carrow Road with a 2-1 victory over the Black Cats with Richardson's late goal not enough for the visitors.
Richardson admits they let the fans down with their performance as they slumped to another defeat.
"I was pleased to score but the result overall is very disappointing," Richardson told the club's official website.
"We were on a high after the Stoke game, but we didn't play well tonight. We had possession in the first half, but it wasn't effective.
"It's a shame because we have let the fans down and I am sorry for that."
Richardson felt Sunderland squandered chances to get back in the game with Connor Wickham wasting a glorious opportunity to open his account for the club.
"I thought we were good enough to get back into the game, but it wasn't to be," added Richardson.
"In the second half, we didn't put our foot on the ball at all. We didn't get in possession, whereas at least we had some of the ball in the first half.
"We still had chances in the second half, though. Connor [Wickham] had a chance with a header and was unlucky - on another day that would have gone either side of the keeper and gone in."
