PAS Giannina goalkeeper Markos Vellidis has already played against PAOK and Olympiacos.
"PAOK are a team that can easily change formations during the game and with Berbatov they are even more dangerous. Olympiacos are in great form, have well-known players like Cambiasso who helps on both ends. I don't think they have obvious weaknesses. Such derbies are not judged in tactics but in passion" said Vellidis.
