With the beginning of the 2005–06 season, Nikl seemed to fall out of coach Wolfgang Wolf's favor playing just five of the eleven games until Wolf's dismissal.
He had the following year a place in the first eleven but after his former Wolfsburg manager Wolfgang Wolf had to leave the club he did not play anymore so he followed him to famous second league club 1. FC Kaiserslautern where he could return to his old strength.
