Alan Pardew admitted his Newcastle side failed to create enough chances after their shock 1-0 exit at the hands of Championship side Brighton in the FA Cup.
The Magpies' boss felt his side lacked real bite in front of goal at the Amex Stadium as Albion stopper Peter Brezovan and some desperate defending stopped the visitors from scoring.
The winning goal was given as an own goal by Newcastle defender Mike Williamson as the impressive Will Buckley's 76th-minute shot struck the defender before looping over goalkeeper Tim Krul.
And Pardew admitted his team had failed to take their chances.
"I felt we weren't threatening their goal enough. They defended well, Brighton, to be fair to them," he told ESPN.
"We had a good grip of the game (in the first half), we felt comfortable.
"We just struggled to get more shots on goal, to get more chances."
Pardew was not surprised his side were not awarded a penalty in the closing stages when Brighton's Ashley Barnes appeared to handle the ball.
Pardew said: "We haven't had one of them all year so we weren't expecting one today.
"I can't really fault my players too much in terms of the commitment they have shown."
