Sporting director Ole Book oversaw a significant recruitment campaign during his first summer transfer window in charge, bringing several promising players to Dortmund, including Joane Gadou, Konstantinos Karetsas and Giannis Konstantelias.
However, Veerman's arrival initially attracted less attention than some of the club's other additions. The 27-year-old was among the players recruited as Dortmund reshaped their midfield, having previously established himself as an influential figure at PSV.
That perception is now changing.
According to Kicker, Veerman is regarded by several people inside Dortmund as the club's unofficial standout signing of the summer, with his performances making an increasingly important difference to the team.
Head coach Niko Kovac has also been impressed by the midfielder's approach, particularly his ability to make difficult things look straightforward.
“What I particularly like about him is his simplicity. There is difficulty in simplicity, but also beauty,” Kovac said.
The comments reflect the qualities that have made Veerman such an important addition. His passing range, technical ability and understanding of the game allow him to dictate the tempo, while his experience provides Dortmund with an established presence in central midfield.
Dortmund secured his services from PSV Eindhoven in August, with Veerman signing a contract running until June 2031.
The Netherlands international had spent several successful seasons in Eindhoven, winning three Eredivisie titles and establishing himself as one of the country's most accomplished midfielders.
His arrival was part of a wider effort to strengthen Dortmund's options in the middle of the pitch following the departures of Pascal Gross and Salih Özcan.
Book was particularly enthusiastic about the qualities Veerman would bring to the squad when the transfer was announced.
The sporting director highlighted his creativity, technical quality and vision, believing those attributes would make him an important contributor to Dortmund's ambitions.
Veerman's experience with PSV and the Netherlands also gives Kovac a player capable of performing at a high level immediately, rather than requiring an extended adaptation period.
The midfielder has already begun to justify that confidence, with his influence growing as the season progresses.
While Dortmund recruited several highly rated young players during the summer, Veerman's performances are increasingly suggesting that the experienced Dutchman could prove to be their most valuable addition.
For a club looking to compete consistently at the highest level, his ability to control matches and provide quality in possession could make him a particularly important figure during the remainder of the campaign.
