They are two of the biggest clubs in the world, both with enough trophies to fill a warehouse.
They are Real Madrid and Bayern Munich.
On Thursday, the giants of European football will meet yet again in the Champions League semi-finals.
We will need a big performance against a strong opponent. Bayern is a great club with great team spirit.Zinedine Zidane, Coach, Real Madrid
It will be the seventh time they have played each other at this stage in the tournament's history, with Bayern winning four of those previous six. They have competed in the knockout stages of the Champions League 11 times, including three times in the last six seasons.
Here's a look at some of their most memorable matchups, either at the semi-final stage or earlier:
2017: Quarterfinals
Their most recent meeting went Madrid's way, thanks to Cristiano Ronaldo.
The Portugal forward scored both goals in Madrid's 2-1 win in Munich, and he then had a hat-trick in the return match to give the hosts a 6-3 aggregate victory.
Two of Ronaldo's goals came in extra time in the second leg at Santiago Bernabeu Stadium, keeping Madrid on track to winning its third title in four seasons.
Bayern had players sent off in both matches — Javi Martinez in the first leg and Arturo Vidal in the second. The German team played the entire extra time in Madrid with 10 men.
2014: Semi-finals
Even with Pep Guardiola calling the shots for Bayern, Madrid eliminated the German team 5-0 on aggregate on its way to another title.
Karim Benzema scored the winner in the 1-0 victory in Madrid. The Spanish team then won 4-0 in Munich to hand Bayern its worst European home defeat.
Sergio Ramos and Ronaldo each scored twice for Madrid in the return match.
2012: Semi-finals
Coached by Jupp Heynckes, who is now back in charge at the German club, Bayern got the best of Madrid on penalties after each side recorded a 2-1 home victory.
An early goal by Franck Ribery and a late winner by Mario Gomez put Bayern ahead in the series, but Madrid rebounded with two goals by Ronaldo in the first 15 minutes of the second leg before Arjen Robben pulled one back for Bayern before halftime.
Neither team could score after regulation and Bayern eventually won the penalty shootout 3-1 as Ronaldo, Kaka and Ramos all missed their shots from the spot.
2007: Round of last 16
Bayern eliminated Madrid on away goals after a 4-4 aggregate draw.
Madrid won 3-2 in the first leg at home, when Raul Gonzalez scored twice, but Bayern advanced with a 2-1 win in Munich after Roy Makaay scored 10 seconds into the match for what remains the fastest ever Champions League goal.
2004: Round of last 16
Zinedine Zidane, the current Madrid coach, scored the decisive second-leg goal that allowed the Spanish team to advance.
Zidane beat goalkeeper Oliver Kahn with a shot from inside the area.
The first leg in Munich ended in a 1-1 draw with goals by Makaay in the 75th minute and Roberto Carlos in the 83rd.
Other Meetings
The teams faced each other in three straight Champions Leagues between 2000-02, with the winner going on to win the title each time.
Madrid won the 2000 semifinal series 3-2 on aggregate and advanced with the same score in the 2002 quarterfinals. Bayern won the 2001 semifinals 3-1 on aggregate, and also got the best of Madrid in the group stage in 2000 with a 4-2 victory in Madrid and a 4-1 win in Munich.
Bayern also won the teams' first two matchups, in the semifinals in 1976 and 1987. Madrid, however, won in the 1988 quarterfinals.
