Arsenal are sitting pretty at the top of the Premier League but have a fight on their hands to stay in Champions League contention.
The Gunners were frustrated during the first leg of their Round of 16 clash with Porto before Galeno scored a superb winner for the hosts deep into stoppage time.
It was an unusually shot-shy performance from Mikel Arteta's side, who have been in free-scoring form domestically over recent weeks.
They will hope to bring that form to bear against Porto and banish an awful record at this stage of the Champions League.
