Last Saturday Arsenal lost 3-1 to United after giving away two simple goals in the first 11 minutes.
The striker left it late, too, superbly glancing his effort into the corner of Southampton's goal with just two minutes remaining to prevent his side from slipping into their second successive Premier League defeat.
"The players wanted to start strong, and overall I believe it took us time to get into the game again".
Wenger was less than pleased, he continued: "We're not happy because we wanted to win but when you can not win at least don't lose".
Charlie Austin fired an early opener for Mauricio Pellegrino's hosts - his fifth in three Premier League starts this season - and the striker was unlucky not to have more to show for the palpable sense of panic he and the Southampton attack injected into a shambling Arsenal backline.
