Jurgen Klopp and Marcelo Bielsa will meet at Elland Road tonight as Leeds United host Liverpool; the two high-profile characters share a number of tactical similarities across the board because of their respective playing styles.
The pair of coaches are wedded to authentic attacking football, with intensity constantly showcased with and - particularly - without the ball on a regular basis.
The names of Klopp and Bielsa are largely associated with pressing, but not all pressing is the same, and the way in which they go about their defensive work differs quite considerably as they approach an upcoming clash that promises entertainment at the very least.
The Liverpool boss is the modern face of counter-pressing, which involves the ball being regained high up the field seconds after being lost, which should - in theory - result in immediate scoring opportunities materialising due to sudden disorganisation.
As a result of that idea, much of the pressure made by the Reds happens in the final third so that the champions can use any ball regains to swiftly attack, with Klopp famously quoted as stating: "No playmaker in the world can be as good as a good counter-pressing situation."
Bielsa is a huge advocate of pressing himself, but he uses closing down as a general defensive approach rather than an attacking tactic like Klopp, which makes him slightly different.
Again, as a consequence, that impacts where his Leeds United team press the ball; rather than primarily focusing on the final third as the Reds do, the Whites are active all over the pitch which makes them unique in comparison to most teams.
Liverpool rank top of the Premier League for attacking third pressures this season with 42.3 per match, followed by Leeds in second on 36.8 per match, as shown below.
However, Klopp's outfit place 10th for middle third pressures and 19th for defensive third pressures per match, which captures the team's tendency to press at the business end of the field above anything else as a means of quickly recovering possession close to goal whenever it is lost.
Leeds, by contrast, rank top for middle third pressures and second for defensive third pressures, meaning that Bielsa's men unconventionally place inside the top two for pressures in each third of the pitch.
Regardless of where the ball is, Leeds will put pressure on the opponent in possession and they do so using a tight man-marking scheme, which is another key factor that differentiates them from Liverpool.
The Reds - rather than man-marking - opt to employ a zonal approach to pressing by ensuring that space is covered around the ball by a compact group of players without specific opponents being picked up, which is one of the reasons behind why Klopp's side tend to suffer from quick switches of play from one side of the pitch to the other.
Pressing is ingrained into the nature of Liverpool and Leeds but when the two sides come together to battle on Monday night, both Klopp and Bielsa will be trying to highlight the weaknesses attached to how their opposite number chooses to do things.
