Yes, I thought Arsenal was going to end that FC Porto record yesterday at Emirate Stadium. FC Porto put on a good fight against Arsenal in the UEFA Champions League's last 16 matches, but Arsenal used home advantage to beat FC Porto with a goal difference.
winning on penalties when they were become a hosts was an unsatisfactory result for Arsenal. But, a win is still a win. Even though Arsenal had to beat Porto on penalties, this is a good result for the gunner, and i believe that can provide morale for Arsenal players so they can play better in the next round.
In other matches, Napoli showed poor performance. I don't know how Napoli management will end this situation after losing to Barcelona in the UCL, Napoli should focus on getting 1 position for UCL next season.
