Ahead of Barcelona's visit to Glasgow, talkSPORT takes a look at some European clashes between the Catalans and Celtic in recent years.
Celtic beat Barca in Glasgow
Three players sent off, a tunnel melee and most importantly, a Celtic win back in 2004. Celtic goalie Rab Douglas and Barca midfielder Thiago Motta were handed red cards in the dressing rooms following a brawl at half-time during this 2004 UEFA Cup clash, then shortly after the teams reappeared for the restart, Alan Thompson slammed the home side into the lead. Ten minutes before Thompson's 59th minute winner, Barca's Javier Saviola was given his marching orders for kicking out at Thompson, reducing the visitors to nine men. Celtic held their nerve to take a crucial 1-0 lead into the second leg.
Celtic hang on for famous win
With 'keeper Douglas suspended for the return leg in Spain, teenage goalkeeper David Marshall put in the performance of a lifetime at the Nou Camp, as Celtic held Barca to 0-0 and progressed to the quarter-finals. Right from the off, 19-year-old rookie Marshall let the Barca superstars know they were going to have a tough job finding their way past him. Young Celtic defender John Kennedy - who was sadly forced to retire on medical grounds in 2009 because of a knee injury - also had a great game, negating the immense attacking talents of Ronaldinho, Luis Enrique, Xavi and co. Sadly, the Celts could not carry on the run against Spanish opposition and were dumped out in the quarter final by Villarreal.
Celtic Park hero returns to haunt the Hoops
A few months after knocking Barcelona out of the UEFA Cup, the two clubs met again in the following season's Champions League. This time Celtic legend Henrik Larsson - who scored 174 goals in 221 league games for the club - returned to Celtic Park in Barca colours to help end his former club's unbeaten home record in the Champions League. Chris Sutton equalised after Deco's first half goal had put Barca ahead, then Ludovic Giuly and Larsson - who had only been on for 20 minutes after replacing Ronaldinho - scored after rounding goalkeeper Marshall to secure a 3-1 win eight minutes from time.
Terrific Thierry silences Celtic Park
They battled hard, but the Bhoys - despite twice taking the lead - were undone by Lionel Messi and a brilliant Thierry Henry strike at Celtic Park in the 2007/08 Champions League last 16. Jan Vennegoor of Hesselink headed the home side in front, but Messi pulled Barca level three minutes later, before Champions League debutant Barry Robson gave Celtic a 2-1 half-time lead. After the interval, Henry's leveller silenced the home support and, with 10 minutes left, Messi inflicted a first home defeat for Celtic in Europe since Barca's 3-1 Larsson-inspired win four years earlier. Barcelona went on to be crowned kings of Europe the following year, putting into context how well Celtic had done to push them so hard.
Barca masterclass leaves Bhoys devastated at the Nou Camp
When Celtic and Barcelona met in 2004, the Glaswegians went into the match as recent UEFA Cup finalists and expected to give the Catalans a good game, but eight years later the two gulf in class between the two clubs was meant to be unbridgable. Not so, as Georgios Samaras gave Celtic the lead in the Nou Camp and held on to their lead with half-time approaching. A moment of magic saw Messi, Xavi and Andres Iniesta combine for the latter to equalise just before the break, despite being surrounded by a host of green and white shirts. Barca finally found a way through on 90 minutes when Jordi Alba broke Celtic hearts, but the performance gave great hope that Neil Lennon's team could progress to the knockout stage for the first time since 2008.
Do you think Celtic will exact revenge for their Nou Camp heartache by taking points off Barcelona?
