At the same time, Tzavellas was rumoured to want to leave Eintracht Frankfurt following their relegation from the top flight. However, his agent, Paul Koutsoliakos, stated: "There is simply no truth in this."Eintracht Frankfurt general manager Bruno Hübner added: "We would refuse to accept any loan arrangements in this respect as something like this would just postpone a permanent transfer for the player. We would be in the same situation in 12 months."[5]
