Mats Hummels is a German professional footballer who plays as a centre-back for Bundesliga club Borussia Dortmund and the Germany national team. He has been instrumental in shaping the attacking capabilities of his team, particularly in the past few seasons.

Hummels' impact on Dortmund's attack can be seen in several ways. Firstly, he provides stability at the back, which allows the forwards to focus more on their attacking duties. This helps to create space and freedom for the likes of Erling Haaland, Jadon Sancho, and other talented players to run forward and score goals.

Secondly, Hummels' presence on the pitch acts as a physical barrier, preventing opposing teams from breaking down the Dortmund defense. This means that Dortmund's forwards have a clear field of play, which makes it easier for them to get into good positions and create scoring opportunities.

Thirdly, Hummels' aerial ability and tackling skills are crucial in maintaining possession of the ball. He often leads the line in defensive situations, which gives his teammates time to organize themselves and win the ball back quickly.

Overall, Hummels' contribution to Dortmund's attack cannot be overstated. His leadership, experience, and defensive contributions have helped the team to consistently perform at a high level, making him one of the most important players in the squad. As such, it is no surprise that he has become a fan favorite and is widely regarded as one of the best defenders in world football.
