Zdenek Zeman took over, Sergen was consistently engaged in trench warfare. Sergen publicly criticised Zeman for trying to play him on the wing, which he believed was not his best position, and was accused of faking injury to avoid training sessions. Along with many other incidents, the final straw came with the home game against Bursaspor. When he eventually came on as a substitute, Sergen missed a simple scoring chance, which many of the fans believe to have been a deliberate miss as an act of protest or just pure spite.

The deal fell through and he instead moved to Trabzonspor and became the first player to have represented the big four clubs in Turkey. Sergen had never yet played
