Belanov's first move at Wil was replacing first-team manager Martin Andermatt with his former Dynamo Kyiv teammate Oleksandr Zavarov, not taking note of the fact that he lacked the necessary UEFA licence to manage a European top-division outfit. That circumstance forced Belanov to sign former FC Karl-Marx-Stadt manager Joachim Müller. Due to the appointment of Müller, Zavarov's job was officially described as director of football; Müller did not last long as coach however, as Belanov sacked him just after three months, replacing him with Tomáš Matějček.
