Borussia Dortmund is one of the most successful football clubs in Germany, and they have a long history of producing talented players who make significant contributions to their team's success. One such player is Borussia Dortmund's midfielder, Sebastian Haller, who has made several key contributions to his team's goals.

One of Haller's most notable contributions to his team is his ability to create assists. He has been known for his creativity on the field and his ability to find space for his teammates. In the 2019-20 season, Haller scored 14 goals and provided 5 assists, which was a remarkable achievement considering he only played 36 games that season.

Haller's assist numbers were even more impressive when you consider the fact that he had a difficult season last year due to injuries. Despite this, he still managed to contribute significantly to his team's success by providing crucial assists for his teammates.

Another important aspect of Haller's game is his work rate. He is always willing to put in extra effort on the pitch and is not afraid to get stuck in between tackles or make a tackle himself. This willingness to give everything he has means that he can be a valuable asset to any team, especially in a position like midfield where he can help set up attacks and provide cover for defenders.

Overall, Haller's contributions to Borussia Dortmund's success cannot be overstated. His creativity, work rate, and ability to create assists make him a valuable asset to any team, and his performances will undoubtedly continue to impress fans and teammates alike.
