Lahm has told The Athletic of Kompany’s methods, with there still room for improvement: "It is obvious that Kompany was influenced by his former coach, Guardiola, who revolutionised modern possession football. Guardiola paid attention to absolutely everything in training. He was like a composer obsessed with every note that his orchestra played and would make his view clear to everyone about everything.
"Kompany is not a copy; every student goes their own way. He also favours possession and wants to dominate the game. His Bayern team defend courageously man-to-man, which means a high level of risk. However, he seems to give his players more freedom than Guardiola.
"The defence has stabilised under Kompany. In recent years, there has been a lack of concentration, no clear hierarchy among the players and many goals conceded. Now Dayot Upamecano and Kim Min-jae seem to form a secure duo. Joshua Kimmich’s role in central midfield is also more clearly defined. Kompany’s signature is evident in his organisation, but also in his patience when playing with the ball.
"Does his attacking style work at the highest level? There is still a lack of evidence. His team have difficulties with their overall balance and a few areas are not operating yet at the highest level. The midfield, for example, is susceptible to counter attacks. The possession can often be too slow, the progress towards goal is sometimes indecisive, and there is a lack of penetration in that final third, where attacks too often break down."
