After last Sunday's hard-fought victory at Stamford Bridge, the Reds secured a 2-1 triumph over the Gunners at Old Trafford thanks to goals from Robin van Persie and a second of the season from Evra himself.
"Accidents can happen and it's happened twice now this season!" he joked to MUTV in reference to his strikes against Newcastle and now Arsenal.
"I'm really happy to score again but the most important thing is the three points. We're a little bit disappointed we didn't keep a clean sheet but in the end it was an important win and that's what everyone was looking for before the game. It's been a terrific week for us."
