A late goal from Nicklas Bendtner earned Arsenal a 2-1 win in the north London derby against Tottenham.
Bendtner had only been on pitch for a few seconds after coming on as a sub, but was left unmarked in the area by the Tottenham defenders.
He was left alone as Cesc Fabregas played in a corner, and Bendtner was able to head the ball into the net.
Moments earlier Robbie Keane missed a penalty for Spurs, after his side had fought back from a goal down.
Emmanuel Adebayor had put the Gunners in front just after half-time, before Dimitar Berbatov netted an equaliser.
Later in the day, Liverpool were also winners after a 4-1 victory at home to Portsmouth.
