After the resignation of Thomas Wüstefeld as CFO and member of the supervisory board of the second division soccer club Hamburger SV, it is unclear what will become of his shares in HSV Fußball AG.

The 53-year-old medical entrepreneur holds 5.11 percent of the AG shares, which he only took over last year. After weeks of allegations against him, Wüstefeld resigned at an extraordinary supervisory board meeting on Wednesday evening, although he always rejected the massive allegations.

The supervisory board accepted the decision and decided that sports director Jonas Boldt "will initially manage the operational business of HSV as the sole board member," HSV announced late Wednesday evening. "I am aware of the responsibility and will tackle the upcoming tasks in very close cooperation with my colleagues in the office as well as with the Supervisory Board and especially with the Finance Committee," said Boldt. The 40-year-old's contract runs until the end of the season.

Wüstefeld had offered the supervisory board and its chairman Marcell Jansen a joint review. Massive allegations have been repeatedly made against the HSV board in connection with his work as a medical entrepreneur in recent weeks. It is about lawsuits worth millions from other entrepreneurs, a possible criminal complaint for breach of trust and allegedly illegally sold medical products that the commission wanted to check.
