Arsenal manager Mikel Arteta apologized for his team's performance after they were knocked out of the FA Cup in the third round for the second time in four years by Nottingham Forest.
Seven minutes from time, Lewis Grabban slipped home Ryan Yates' inviting cross to stun the 14-time champions.
Arteta said, "We were not good enough and we have to apologise for it,".
"We needed more drive, more hunger to win at any cost in every single action, much more. We were not at our level.
"I'm really disappointed with the performance, first of all. Not with the attitude but how much purpose we have and what determination we showed to change the game when it's difficult to play against the way they play.
"I have played in games like that for the past 18 years and I know how complicated it is to come here. It's no surprise the difficulties you are going to face. But when we do that, we have to face it in a different way.
"It is really hurting. It is a competition that is very related to our history and to get out of it is a big bump."
The Gunners thought to have witnessed a turnaround in recent weeks, but their performance against their Championship opponents was nothing short of lacklustre.
Despite Arteta's multiple substitutions, England winger Bukayo Saka, Norway playmaker Martin Odegaard, and in-form Gabriel Martinelli all started at the City Ground.
Forest, who have resurrected under manager Steve Cooper, now face an East Midlands rivalry and a fourth-round match against Premier League holders Leicester City.
