Arsenal winger Nicholas Pepe admits the team has a problem with concentration as they lost 1-0 to Manchester City.
The Gunners were asleep at the back as Raheem Sterling leaped higher than their defenders to give City a lead in the first minutes.
City never looked back, and Arsenal were unable to get a foothold in the game.
"We have concentration problems, we need to fix that," Pepe told RMC Sport.
"We had chances in this match as well.
"In this game, there was that goal and then there was nothing."
