Jurgen Klopp's Borussia Dortmund was a highly successful team that emphasized high-tempo pressing, while also preventing opponents' penetrative plays, and was 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. Players either applied aggressive pressing high up the pitch or waited for the opponent in the middle third. Klopp did not hesitate to use both defensive approaches during a game, so there were periods when his players waited for the opponent in the middle third but also intervals when they applied intense pressing. When Borussia's players waited for the opponent, the team maintained its cohesion while immediate pressure was applied to players receiving the ball between the lines. Additionally, the midfielders aimed to block penetrative passes from defenders to 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 and as high up the pitch as possible.
