Arsenal are now two points adrift of League leaders Manchester City, thanks to a late but controversial goal from Laurent Koscielny.
Typical with Arsenal, we dominated the game from the first half but created no little or no chance in both halves of the match.
However, Laurent Koscielny deflected an Oxlade Chamberlain ball in what culminated into a scrappy win.
But he admits he doesn’t know what happened.
“I don’t know if it was handball. I tried with my right foot and I don’t know if I touch it with my hand,” he told Sky Sports.
“The referee gave the goal and you need to respect the decision.
“It was a hard game.
“We had the chance to score but we have to push ourselves on the pitch and it arrived at the end. It keeps our run going.
“We wanted to finish before the international break with a win. It’s important to keep our feet on the ground.
“You could see against Burnley they played well.
“We needed to push ourselves more and more and in football the aim is to win and keep the quality of our football at the same time.”
