UCL : Kekalahan kedua : Arsenal 2-3 Olympiacos

• Olympiacos took the lead on 33 minutes when Arsenal failed to clear a corner and Felipe Pardo's shot deflected in

• Theo Walcott levelled for the home side moments later when he slotted home after Alexis Sanchez had found winger

• A howler by David Ospina gave visitors the lead going into half-time after he appeared to drop the ball over the line

• The scores were then level again when forward Sanchez latched onto Walcott's delivery and headed in off the post

• The Greek giants scored less than a minute later to take the lead once again thanks to Alfred Finnbogason's tap-in

Aaron Ramsey (centre) and his Arsenal team-mates appear to realise the extent of their defeat as Olympiacos seal a late victory
