The last time we came back to win in Europe?
David O'Leary is marked by Hadjuk defenders - including Boro Primorac - at a corner
On Tuesday night Arsenal will try to do what they have not done for more than 30 years - overcome a first-leg deficit to win a European tie.
That 2-1 defeat in Porto a fortnight ago leaves Arsene Wenger's men needing to win 1-0 or by two goals to go through (although a 2-1 win will force extra time and, perhaps, penalties). And there is plenty at stake with a place in the last eight of the Champions League awaiting the winners.
Three of Arsenal's recent Champions League campaigns have ended following an away defeat: they lost at Bayern in 2005, PSV Eindhoven in 2006 and Manchester United last season and failed to turn the tie around on home soil. But it was a different story in the 1978/79 campaign.
Arsenal, under manager Terry Neill, lost the first leg of the UEFA Cup Second-Round tie 2-1 to Hadjuk Split in Yugoslavia. Liam Brady scored what would prove to be a priceless away goal in the tiny Hadjuk stadium.
Back at Highbury two weeks later, Arsenal needed two things: a clean sheet and a goal. They got both with Willie Young scoring a late winner on the night as Arsenal squeezed through on the away goals rule. Arsenal fans would welcome more of the same on Tuesday night.
Note: In the Hadjuk team back then was a very familiar face - Arsenal first-team coach Boro Primorac. You can just about see Boro in the picture above - he is partly obscured by David O'Leary.
