Our round of 16 first-leg ended in defeat after a last-minute long-range effort from Porto gives them the advantage heading into the return fixture at Emirates Stadium.
Neither side could be separated for most of the match with each team missing big chances in the final third, until the 94th minute in added time when Galeno's curling strike found the back of the net.
