There was a worrying moment in the final stages of the 1-0 win over Leicester when Laurent Koscielny went down with nobody anywhere near him.
The French defender seemed to land awkwardly, causing a hyper-extensions of his knee, but after some treatment he was able to play on.
However, Arsene Wenger seemed to suggest that Koscielny may well be a doubt for Sunday’s North London derby.
Asked about the extent of the problem, he said, “Koscielny has a knee problem, I don’t know how long yet.
“I have to check.”
It would be a big blow to be without him, so let’s keep fingers crossed there.
On the win itself, Wenger said, “We took the initiative. We lacked a little bit a change of pace or penetration.
“You could see we had some heavy legs, but we were serious. We didn’t give a chance away. Maybe we lacked a bit of speed in our game to get them out of position but they defended well.
“In the end the win I think rewards the team who took the initiative in the game.”
