VIDEO: Conceicao reflects on FC Porto's dramatic 1-0 victory vs Arsenal

Porto soured Arsenal's return to the last 16 of the Champions League after seven years when the Portuguese side claimed a dramatic victory thanks to a stoppage-time goal from Galeno, who has been in fine form for Sergio Conceicao's side this season.

The Dragons travel to London to face a tough second leg against the Gunners at the Emirates Stadium with a slender 1-0 lead, something Mikel Arteta is confident his side can turn around in front of their fans.

The Portuguese coach spoke about the hard-fought win over the English side and praised his side's "almost perfect" defending to prevent top attackers like Arsenal's from creating dangerous chances. Take a look at what he had to say.
