One of Celtic’s most famed European victories came in their 2012/13 UEFA Champions League campaign when they defeated Barcelona at Parkhead.
The Hoops put the Catalonian giants to the sword in a far-from-dominant 2-1 victory.

Neil Lennon’s side took a highly pragmatic approach to proceedings, sitting back, absorbing pressure, and taking the few chances they created.
Victor Wanyama and teenage substitute Tony Watt scored for the Bhoys on one of Celtic Park’s most memorable European nights.
Angry Aftermath
Although Lionel Messi got one back for the visitors late on, it wasn’t enough. Barca fell to a humbling defeat, and Charlie Mulgrew, who started on the night, has explained just how angry their players were at full-time.
Indeed, the utility man agreed to swap jerseys with Andres Iniesta post-match and revealed how the Barcelona players were incensed with each other in their own dressing room after the final whistle.
“I arranged to swap shirts with Iniesta,” he said (UndrTheCosh Podcast).
“I walked up to the [Barcelona] changing room, and they were all fighting with each other. Messi, Valdes, and Fabregas were all pushing and grabbing and having to get split up.
“I was stood at the door, like ‘Yas! This is brilliant to see how much it means to them’.”
Celtic’s defensive solidity and defiant display rattled Barcelona’s world stars, causing them to fight amongst each other at full time.
The famous victory remains one of the greatest in the Hoops’ history.
Fans argue that Brendan Rodgers and Co. should take inspiration from wins and performances like that to avoid continual scalpings on the continent.
The boss’ open and expansive style of play sees the Bhoys embarrassed against Europe’s elite. Supporters want to see things tightened up against Atalanta next Wednesday.
