Pep Guardiola and Jurgen Klopp will go head-to-head for the 10th time as managers when Manchester City host Liverpool on Nissan Super Sunday.
It is a rivalry that started in the Bundesliga, and is now developing in the Premier League, with Klopp having won five of their previous meetings compared to four wins for Guardiola.
Ahead of City v Liverpool on Sky Sports, we look at how their previous clashes have unfolded…
It was Klopp who came out on top in the first meeting against Guardiola as Borussia Dortmund beat Bayern Munich 4-2 in the German Super Cup in 2013.
The game was Guardiola's competitive debut with Bayern. "Even though we lost, I didn't get the feeling that Dortmund were better than us," he said afterwards.
Guardiola levelled up the head-to-head when the two sides met in the Bundesliga, winning 3-0 to record Bayern's first league victory over Dortmund since February 2010.
Dortmund returned the favour later in the season with a 3-0 victory at the Allianz Arena, but Bayern had already wrapped up the league title by then.
The two sides would meet once more in the 2013/14 season in the German Cup final, with Arjen Robben and Thomas Muller scoring to seal a 2-0 win for Bayern and the double for Guardiola in his debut season.
Again it was Klopp who won the first meeting of the season as Dortmund beat Bayern 2-0 in the German Super Cup, with Henrikh Mkhitaryan and Pierre-Emerick Aubameyang scoring the goals.
But that would not be a sign of things to come as Guardiola's Bayern won both league meetings - 2-1 at the Allianz Arena and 1-0 at Signal Iduna Park.
Just over a week after the home defeat, Klopp announced his departure from Dortmund at the end of the season.
And he finished his rivalry with Guardiola in Germany with a win as Dortmund beat Bayern on penalties in the semi-finals of the German Cup.
The rivalry resumed on New Year's Eve in 2016 as Liverpool hosted Manchester City in the Premier League. Speaking before the game, Guardiola described Klopp as the best attacking coach in world football.
But it was defences that were on top at Anfield, with Georginio Wijnaldum's eighth-minute header separating the sides as Liverpool won 1-0.
"It was really hard work," said Klopp. "But it was not that we were expecting something different. Against Man City, you have to work for three points. If you are good enough, you can get them - and we were good enough."
