Arsenal dropped points against Burnley as they played out a 1-1 draw against the Clarets at Turf Moor on Saturday.
Arsenal took the lead through the club captain Pierre-Emerick Aubameyang but failed to build on that as Granit Xhaka's mistake cost the Gunners all three points away from home.
After the game, Mikel Arteta spoke about the mistake made by the Swiss midfielder as he claimed it was a mistake that happens in football but he demands more from his players.
Arsenal boss Mikel Arteta speaking to BBC Match of the Day: “If you don’t score your big chances, if you give a goal to the opponent and you don’t’ get the referee’s decision when you need to it is very complicated in the Premier League to win a lot of games.
“When you have those moments in the game when you are so dominant you have to go two or three goals up and the game is over. We gave them a goal, it can happen in football and I demand that we play the way we do. Like the first goal we score is all the way from Bernd [Leno].
“It can happen when you play long. The only chance Burnley had was from a long goal kick from Bernd. So you need to know when to do it.
“If the first one is not a penalty honestly someone has to come to the training ground and explain what a handball is. It cannot be any clearer.
“We hit the bar and the post, they cleared the ball off the line but they defend those situations well but it is down to us not getting the three points.
“The top teams sustain results and level through 10 months in this competition and you have to come here and win the game comfortably in my opinion."
