A late-night thriller via penalties was never on the cards. In fairness to Porto, just like the first leg, they were rigid, stubborn and up for the fight.
For Arsenal, the price of this victory is insurmountable. A quarter-final spot in the Champions League for the first time in 14 years awaits.
Of course, they, as many prediction makers said beforehand, expected to do the business within regulation time.
Porto are a good side. But, as the Liga Portugal table reads, are third in their league, seven points behind leaders Sporting Lisbon.
