Arsenal striker Nicklas Bendtner atoned for a poor performance over the weekend to score a hat trick in a 5-0 win over FC Porto for the Gunners to advance to the quarterfinals of the Champions League on Tuesday.

Arsenal overturned a 2-1 deficit from the first leg last month to advance 6-2 on aggregate.

The Denmark international scored in the 10th minute, sliding in to poke the ball into the back of the net. Bendtner scored again in the 25th, tapping in from close range after Andrei Arshavin crossed from the left.

Samir Nasri and Emmanuel Eboue scored within three minutes in the second half. Bendtner added a penalty in injury time.
