Celtic face old adversaries Atletico Madrid in the Champions League group stage at Celtic Park tomorrow night.
The Scottish champions need to take something on Matchday Three if they are to keep alive their automatic qualification hopes.
Brendan Rodgers' side are in fine fettle domestically and their tales will be up after a morale-boosting 4-1 Premiership victory at Tynecastle on Sunday but the La Liga outfit are certainly a class apart.
Celtic supporters are still wanting revenge for the events of 1974 when Atletico ended up with eight men after earning a 0-0 draw at Parkhead amid shameful scenes in the first leg of the European Cup semi-final tie.
The Spaniards advanced to the final after winning 2-0 in Spain but the names of Ruben Ayala and Ruben Diaz are still mud down Glasgow's East End.
The mind games have already started in this one as Atletico cranked up the heat by announcing they will be wearing a special replica strip to commemorate that infamous match at Parkhead which is still widely regarded as one of football's dirtiest-ever games.

Diego Simeone's team are currently fourth in La Liga and stand just three points off Barcelona but they do have a game in hand.
They warmed up for this clash at Celtic Park with a convincing 3-0 away win over Celta Vigo with French international striker Antoine Griezmann netting a hat-trick.
Griezmann has already a fired out a warning to Celtic by stating that it is his dream to win the Champions League and that he is coming to Glasgow to win.
He told the Daily Record: The most important thing for a striker is to score goals. When you are scoring it gives you the confidence that you are going to keep scoring. I feel like I am in some of the best form of my career. I feel like I can go to Glasgow and score goals.
“It is always nice to score, but goals on the big occasions in the big stadiums is extra special. It is my dream to win the Champions League. It has always been my dream. And we are capable of that. We have a coach who always makes it clear to us not to look beyond the next game, so that is what we do. We want to go and win in Glasgow and then it is back to La Liga.”
Celtic will go on in search of their first Champions League group stage win at home in a decade as they hope to pull off mission impossible against Atletico.
