Arsenal 5 Porto 0 (Agg: 6-2):Nicklas Bendtner grabbed a hat-trick as Arsenal cruised into the quarter-finals of the Champions League with an emphatic victory over Porto. Arsene Wenger's young team rose to the challenge as Bendtner was joined on the score sheet by Samir Nasri and Emmanuel Eboue.
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.
The Gunners went ahead after 10 minutes. Goalkeeper Manuel Almunia, standing in as captain, booted a long clearance up field, which Arshavin nodded back for Nasri.
The Frenchman knocked a quick pass between the centre-backs for the Russian to run onto. In tracking back, Porto defender Fucile clattered into his keeper, and Bendtner was first to react, stabbing the loose ball into the empty net.
With the tie now level, Arsenal looked to go ahead, as Abou Diaby hooked a 12-yard effort over. Porto continued to pass the ball crisply, but were undone again on 25 minutes.
Fucile’s poor clearance was latched onto by Arshavin. The diminutive Russian weaved into the left side of the penalty box, before pulling the ball back along the six-yard box to Bendtner, who, despite what he showed here on Saturday, just could not miss.
Arsenal were somewhat fortunate when Brazil forward Hulk — who is serving a four-month domestic ban for a fracas with a steward after a match against Benfica — capitalised on a mistake by right-back Gael Clichy and cut in towards goal, but stabbed his shot into the arms of Almunia.
There was a scare at the start of the second half when Tomas Rosicky gave the ball away to Hulk, but fortunately for the Czech winger, the Porto striker was again off target. Almunia then had to be on his toes as Falcao drove in a low snapshot, which the Spaniard gathered at the second attempt.
Rosicky, who appeared to be carrying a knee problem, was replaced by Emmanuel Eboue just before the hour as Wenger looked to breathe new life into his side.
Arsenal, though, were anything but convincing at the back — with Nasri clearing a header from substitute Cristian Rodriguez off the line. The Frenchman, however, then settled any nerves with a quite brilliant individual goal after 64 minutes.
After collecting the ball just outside the area on the right, Nasri twisted past three Porto defenders before drilling a low shot in off the far post from the tightest of angles.
Safe passage to the quarter-finals was assured three minutes later when, following a Porto corner, Arshavin broke quickly down the left, holding the ball up before releasing the on-rushing Eboue, who rounded the keeper and stroked in a fourth.
Eboue was brought down for by Fucile to concede a penalty in the final minute — which the young Dane stroked into the bottom corner to collect the match ball.
