Galeno's late wonder strike means there's work for Arsenal to do in their Champions League round of 16 second leg against Porto on Tuesday.
The Gunners were riding a wave of momentum heading into the first leg but succumbed to Sergio Conceicao's savvy and diligent outfit which has set up an enthralling return leg in north London.
Arsenal are aiming to progress into the quarter-finals of this competition for the first time since 2010.
Mikel Arteta's side have won eight straight games in the Premier League, looking imperious while doing so, and supporters must be confident of a Tuesday night turnaround.
Porto, meanwhile, have found another gear in recent weeks. A 5-0 thumping of Benfica thrust them back into Primeira Liga title contention and they extended their winning run to six matches across all competitions at the weekend.
Here's preview of Tuesday night's Champions League round of 16 second leg.
