And while United were gutted to miss out on going three points clear at the top, Ferguson says they got a psychological boost from Arsenal's celebrations.
"That's twice in two years they've turned the game around and got something in the last minute, so we were definitely disappointed to come away with a draw.
"Meanwhile, their dressing room was elated. They were celebrating as if they'd won the World Cup, which I found very interesting. Our players took something out of that, psychologically.
"I think we're a better team than Arsenal now. They're a young team and they're going to be a very good team - there's no question of that - but we went there when they were on top form and they hardly managed a shot on goal. There were definitely a lot of positives for us."
