Celtic's Champions League tussles with Barcelona
"We're back where we belong," stated Celtic's chief executive Peter Lawwell after the Champions League group stage draw in Monaco.
Certainly, being drawn against Barcelona in Group C, along with Manchester City and Borussia Monchengladbach, had a familiar look about it.
When Celtic line up against Barca at the Nou Camp on Tuesday, it will be the ninth time the teams have met in the Champions League.
Before that, the clubs played one another in the Fairs Cup in 1964 and in the Uefa Cup in 2004.
From those 12 matches, Celtic have registered two wins to Barca's seven, with three games drawn.
Here's a reminder of how Celtic have fared against their illustrious opponents in Europe's premier competition.

Celtic had captain Scott Brown sent off as Barcelona, missing the injured Lionel Messi, avenged the previous season's defeat in Glasgow.
Cesc Fabregas was the match-winner, heading in with 15 minutes left.
Despite enjoying 82% possession across the game, the breakthrough for the Catalans only arrived after Brown had been shown a straight red card for kicking out at Barcelona forward Neymar.
Brown flailed a foot that caught the Brazilian on the arm and, despite Celtic protestations, he was dismissed.

11 Dec 2013: Barcelona 6-1 Celtic
Barcelona handed Celtic the harshest of Champions League lessons by producing a near-perfect display to equal the visitors' heaviest European loss.
Gerard Pique opened the scoring and Barca added two more goals late in the first half through Pedro and Neymar.
Brazilian Neymar, a £49m summer signing from Santos, added two more before the hour mark to complete his hat-trick.
Cristian Tello completed Celtic's misery, with Georgios Samaras's late headed goal scant consolation.
