Five-star Arsenal smashes Porto

Nicklas Bendtner grabbed a hat-trick as Arsenal cruised into the quarter-finals of the Champions League with an emphatic 5-0 victory over Porto at the Emirates Stadium.

The Gunners were trailing 2-1 from the first leg and had to do without injured captain Cesc Fabregas.

However, Arsene Wenger's young team rose to the challenge as a first-half brace from Bendtner - who missed a string of chances against Burnley here three days ago - was followed by fine goals from Samir Nasri and Emmanuel Eboue before the young Dane slotted home a penalty in the final minute to secure a place among the last eight of Europe's elite once again.

The result also broke Arsenal's unwelcome near 32-year run of failing to overturn a first-leg deficit in a European tie since beating Hajduk Split in 1978.

In the other second-round tie on Tuesday night, a stunning strike from Arjen Robben fired Bayern Munich into the quarter-finals at the expense of an unlucky Fiorentina at a wet and windy Stadio Artemio Franchi.

The Germans, leading 2-1 from the first leg, were second best for long periods of the game and had looked to be on their way out of the competition when Juan Vargas and Stevan Jovetic scored the game's opening two goals to put the hosts ahead in the tie for the first time.

But Jovetic's strike sparked a manic 11-minute period during which four goals were scored and Bayern took an unlikely grip on the game.

Van Bommel levelled the tie with a low drive on the hour only for Jovetic to score his second four minutes later.

That sparked wild celebrations from the home bench, but just 72 second later Robben, who had been well marshalled until that point, broke free of his markers to unleash an unstoppable 30-yard strike to settle the contest on away goals.
