Real Madrid first came to Scotland in 1960, playing a part in arguably the greatest game of all time.
Ferenc Puskas scored four as Alfredo Di Stefano netted three at Hampden in a remarkable 7-3 win over Eintracht Frankfurt in the European Cup final at Hampden.
They returned three years later to beat Rangers 1-0 at Ibrox in September 1963, adding another six goals without reply in the second leg in Spain.
Their next visit was to face Kilmarnock in November 1965, drawing 2-2 in Ayrshire, before seeing off the Scottish champions 5-1 in Madrid.
On their next visit in 1980, they lost 2-0 to Celtic in Glasgow before turning the tie around two weeks later with a 3-0 home win.
Tuesday night’s visit to Celtic Park on Champions League duty will be the sixth time the most successful team in European football history has taken to a Scottish pitch in competitive action.
Most recently, they lifted biggest title in club football, again at Hampden, in 2002 when Zinedine Zidane’s stunning volley saw off Bayer Leverkusen.
But, in their most notable clash with a Scottish side in Europe, they were conquered by Alex Ferguson and Aberdeen in the 1983 European Cup Winners’ Cup final in Gothenburg.
Here, in pictures, is a look at Real Madrid’s relationship with Scotland.
