Lauren rolled home a late penalty to win another frenetic north London derby just minutes after Teddy Sheringham's superbly dispatched spot kick looked set to earn us a point and hand Arsenal a title setback at Highbury.
Wenger suggested we shouldn't have been awarded that penalty in the first place. "I couldn't believe it," he said. "The important thing was how we would react and I was confident we would react strongly.
"There was a lot of tension and nerves but we found the mental strength to bounce back. It was an important victory as it is still in our hands.
"The fact that we won will give us even more belief. Now our performances will decide. We are very confident and we have a great belief in our team that we will do it.
"Manchester United won earlier against Leicester but that just shows our strength as we were under pressure as we knew we could not slip up."
Arsene Wenger claimed Arsenal showed the nerve needed to win what will surely be the Gunners' toughest home test for the rest of the season.
