Arsenal boss Arsene Wenger admits his tem have surprised himself this season.
Victory at Cardiff City sees Arsenal now seven points clear at the top of the table.
Wenger said: "No, I wouldn't have believed it. Remember we lost the first game at home to Aston Villa and no one could imagine the situation today (Saturday).
"That's why we have to keep a level of urgency. I'm happy to have done the job here and we can watch the other games tomorrow (Sunday). All we can do is do the job and prepare for the next game."
