Jurgen Klopp is one of the only managers in world football who has proven over time he can go toe-to-toe with Pep Guardiola.
The rivalry between the game’s most intense and innovative coaches began in July 2013 when Klopp’s Borussia Dortmund beat Pep’s new club Bayern Munich 4-2 to win the German Supercup.
Overall, their current record is five wins apiece with two draws from their dozen head-to-head encounters.
Whoever emerges victorious from the greatly-anticipated Champions League quarter-final between Liverpool and Manchester City will take a step closer to club football’s biggest prize, but also personal satisfaction for beating a long-standing adversary.
