Arsenal boss Mikel Arteta was disappointed with how they performed against Burnley in the Premier League.
The Gunners were held to a 0-0 draw at home by the bottom placed club in the league on Sunday.
Arsenal missed out on a chance to move into fourth place in the league heading into the mini winter break.
"We have to find a way to win those games if you want to be fighting with the top teams," Arteta told the club's website.
"We didn't start the game well enough, not quick enough, everything was a bit leggy and slow, it would come up and it doesn't.
"It's true in the first half we picked it up in the last 15, 20 minutes and we came out in the second half really strong and we had a different kind of intention.
"We were more incisive, we penetrated much more, the speed of the ball was better, we were playing forward much more, we had runs in behind, we had the right width, but at the end we didn't show enough quality in those last 20 metres and in the box to win the match."
