Peter Bosz: The protagonist of Borussia Dortmund's rise in the Bundesliga this season

It came as a shock when Borussia Dortmund sacked manager Thomas Tuchel a few days after his side lifted the DFB Pokal. When Peter Bosz was announced as the new manager, the fans were a bit surprised with the appointment. But after seeing Dortmund's performances so far this season, the early scepticism has vanished.

Peter Bosz was mostly known for his youth philosophy in Netherlands, which fits perfectly well with the system at Dortmund. At Ajax, he developed young players --Kasper Dolberg, Hakim Ziyech and Davinson Sanchez to name a few -- who were integral in Ajax reaching the UEFA Europa League Final, only to lose to Manchester United.

At Dortmund, he already has the services of young players like Alexander Isak, Raphael Guerreiro, Julian Weigl and Christian Pulisic. He has brought some young blood in Mahmoud Dahoud, Maximilian Philipp, who have already become an integral part of the senior squad.

He brings a completely new system of play, different from Jurgen Klopp and his disciple Thomas Tuchel, which the players have managed to implement fairly well. Despite losing an incredible player like Ousmane Dembele to Barcelona, the work he did to replace the outgoing Frenchman was commendable.

Soon after the departure of Ousmane Dembele, he brought in players like Andriy Yarmolenko and Jadon Sancho from Dynamo Kyiv and Manchester City respectively.

Now, after just seven Bundesliga matches, Dortmund are sitting at the summit with 19 points and 21 goals scored, conceding only two in the process. The Yellow Wall of Dortmund is seemingly proving tough to break down for most Bundesliga teams. Peter Bosz's style of tactics combines that of Jurgen Klopp's Gegenpressing and Pep Guardiola's style of keeping possession of the ball using a quick passing technique.

The trainer has introduced a new rule at Dortmund; a player should not keep possession of the ball for more than two seconds. This rule is also known as the "2-second rule".

Bosz prefers a 4-3-3 system, with a possession-based approach, which is typical Dutch football. This system is mostly based on individual creativity of players. When the opposition has the ball, the whole team presses with high intensity. Sometimes this system can lead to huge gaps in the defence and ultimately conceding a goal (their Champions League campaign perhaps exemplifies the aforementioned).

Regardless, winning the ball back in dangerous areas has always been a hallmark of their pressing charge. After winning the ball back, their team spreads, using all the width of the pitch which ultimately results in openings up front.

It has been so far, so good for Peter Bosz and his Dortmund team. His new system has shown phenomenal results till now. But, only time will tell if this will be enough to propel Dortmund to win the Bundesliga title this year and dethrone Bayern Munich, who have been dominating German football for five years now.
