Arsenal manager Arsene Wenger has admitted that his side "lacked a bit of sharpness" in their 1-1 draw with Manchester United at Old Trafford this afternoon.

The Red Devils had been on course for all three points thanks to Juan Mata's 68th-minute opener, but substitute Olivier Giroud salvaged a point for the visitors with one minute of normal time remaining.

Speaking afterwards, Wenger conceded that his charges had put in a below-par performance but admitted that he was still pleased to walk away from the encounter with a positive result.

"The result in the end is positive for us because we were 1-0 down with two minutes to go. For the rest it was a bit of a scrappy game with two teams well organised who defended well," Wenger told Sky Sports News.

"Our passing was not quick enough, our penetration was not there and in the end we looked like we had good possession of the ball but not many chances. In the second half we suffered for the first 20 minutes and they deserved to be in front.

"The players who came on made a massive difference today. When you are 1-0 down and come back to 1-1 of course you have to feel happy. We lacked a bit of sharpness today, what is it down to I don't know but at least we came back."

The Gunners now face back-to-back home fixtures, welcoming Paris Saint-Germain in the Champions League in midweek before Bournemouth visit the Emirates in the league next weekend.
