The Jurgen Klopp's Borussia Dortmund was a very successful team that emphasized pressing with a high tempo, while also preventing the opponents' penetrations, while being ready to transition from attack to defense during the attacking phase. Jurgen Klopp led Borussia to two German championships, one cup, and a Champions League final in 2013.
Borussia used a mixed defensive approach. The players either applied aggressive pressing high up the field or waited for the opponent in the middle third. Klopp did not hesitate to use both of these defensive approaches during a match, so there were periods when his players waited for the opponent in the middle third but also periods when they applied intense pressing. When Borussia's players waited for the opponent, the team maintained its cohesion while applying immediate pressure on the players receiving the ball between the lines. Additionally, the midfielders aimed to block penetrating passes from the defenders to the attackers. This tactic favored counterattacks and led to the creation of many opportunities. During the negative transition, the team attempted to regain possession as quickly as possible and as high up the field as possible.
