Arsenal manager Mikel Arteta admits his side have to stop committing individual errors.

The Gunners put in a disappointing display in the Champions League group stages on Tuesday.

Having won their first game at home against PSV Eindhoven, Arsenal were beaten 2-1 by Lens in France.

Post-game, Arteta stated: “Yeah we want to stop everything and produce big possibilities for the team to win the game. But they are part of it and errors happen in football constantly, every three or four seconds an error will happen, yours or the opponent, and we have to adapt to that.

“Today the situation was that we had more control, especially after the first goal, and we had two big chances to score before them and then the game turned around in that situation when they played around us and we defended the box really poorly. But that is what happens. Big teams punish you and today we did not punish them in the way we punished PSV."

Asked if goalkeeper David Raya making a mistake disappointed him, Arteta added curtly: “No."
