Arsenal boss Arsene Wenger lamented his side's inability to take their chances after the Gunners conceded a stoppage-time equaliser in the 2-2 derby draw with Tottenham Hotspur.
The Gunners looked to be coasting towards the points - and a third victory of the season over their north London rivals - after goals by Kolo Toure and Emmanuel Adebayor had given them the lead following Robbie Keane's opener for Spurs.
But Jermaine Jenas struck deep into stoppage time to secure a point for Spurs and left Wenger bemoaning his side's lack of composure in the front of goal.
"We should have won by five goals," he said. "We didn't see Spurs creating many chances but they scored two goals.
"It's the story of the season. Fantastic spirit but we have to learn to make the most of our chances.
"We hit the post three times and I think we should have scored at least five times.
"The basic ingredients are fantastic and we produced some exciting football."
Wenger also admitted he was hoping to win the match in honour of vice-chairman and close friend David Dein, who left the club this week after a boardroom falling out.
"We wanted to give victory to David today," added Wenger.
But the Frenchman denied the off-field wrangling during the week had taken its toll on the players.
American sports magnate Stan Kroenke is reportedly lining up a hostile takeover bid for the club which led to a split at boardroom level this week.
"You have to focus on your own performances," said Wenger. "There is always something happening at a big club.
"It's down to the mental strength of the team and we showed we had plenty of that."
