Bendtner hat-trick sinks Porto

A hat-trick from Nicklas Bendtner helped Arsenal to a 5-0 thumping of Porto yesterday as they overturned a first-leg deficit with ease to reach the quarter-finals of the Champions League.

Samir Nasri and Emmanuel Eboue were also on target as Arsenal completed a 6-2 aggregate victory to reach the last eight for the third consecutive season.

Arjen Robben's superb strike sent Bayern Munich through to the quarter-finals on away goals yesterday despite a 3-2 defeat by Fiorentina in a thrilling last 16 second leg in Florence, Italy.

The Dutchman found the net from 25-metres with a wind-assisted shot in the 65th minute to make the aggregate score 4-4 after the four-times European champions won the first leg 2-1.

Fiorentina's Juan Manuel Vargas took advantage of a Hans-Joerg Butt fumble for the opener in the 28th minute and Stevan Jovetic made it 2-0 for the hosts in the 54th before the home crowd went on an emotional rollercoaster ride that ended in disappointment.

Mark van Bommel levelled the tie for Bayern in the 60th before Jovetic bagged his second, only for Robben to decide it with his strike almost immediately after.

Bendtner was guilty of a series of bad misses in the Premier League win over Burnley at the weekend but he answered his critics in style with a commanding performance to crown a dazzling display by manager Arsene Wenger's side.

"It shows how quickly football can change," Wenger told Sky Sports. "I hope it won't give him too much confidence now.

"But it's good for him especially after Saturday. I hope it will give him the desire to work even harder."

Porto had never won a European fixture in England before but Arsenal's poor record of overturning first-leg deficits, a feat they had not managed for more than 30 years, gave the Portuguese side hope of defending their 2-1 advantage.

That hope did not last long on a chilly north London night as they were completely outclassed.

"They controlled the match," Porto coach Jesualdo Ferreira told reporters. "They played very well but I don't think we deserved to lose by five goals.

"Arsenal are very good at provoking the opportunities they need and they have the quality to seize those moments. This defeat hurts."

Injured Arsenal skipper Cesc Fabregas, whose midfield playmaking role was filled superbly by Nasri, said in his programme notes he hoped Bendtner had saved his goals for Porto after his blunders against Burnley.

After 10 minutes the Danish striker duly obliged when he slotted the ball into an empty net after keeper Helton had bravely denied Andrei Arshavin who had been released by Nasri.

Arshavin's pace and trickery teed up Bendtner for his second on 25 minutes as Arsenal moved ahead on aggregate. Two goals in four minutes just past the hour killed off the visitors.

After 63 minutes Nasri ran at pace into the Porto area and dribbled past three defenders before planting a shot inside the far post.

Then Arshavin carved Porto open and his reverse pass allowed Eboue to roll the ball into an unguarded net.
