Arsenal manager Arsene Wenger admitted that the North London Derby defeat should be archived as a frustrating afternoon as the Gunners lost by two goals to one.

Speaking after the game, the Frenchman declared that it was as if his players started the game with the “handbrake on” although they still managed to create four goal-scoring opportunities with the manager believing that even when the Gunners found the equalising goal they still could have pushed more to find the lead.

Asked about the late injury suffered by right-back Bacary Sagna, Wenger concluded by saying that the medical staff is very worried as they have to make checks to the fibula in the ankle of the French defender.

Sagna will join Thomas Vermaelen and Johan Djourou on the sidelines and will miss three months of action as confirmed by the Club’s official website with young Carl Jenkinson to be promoted to regular on the right wing.

After the Spurs defeat, Wenger said:

[A frustrating afternoon?] Yes, because in the first half I felt we played a little but with the handbrake on. Even playing like that we had four chances.

At half time we came out and had a go at them and got it back to 1-1. I felt again that we didn’t push on enough and let them get back into the game. We lack a little bit of confidence at the moment, and we just need to protect a result when we have one.

[Bacary Sagna?] We are very worried about his injury. He is in hospital at the moment and it is too early to say but the first signs do not look good at all.

It is the fibula in the ankle that has to be checked, that is what I have been told. We will know tonight.

I think he was pushed quite hard by Assou-Ekotto and I’m not sure what happened to him.

He might have landed the wrong way, I don’t know. I will have to see it again. Straight away he wanted to be substituted.
