 In September 2006, Lemonis once again replaced Ioannis Matzourakis, this time as coach of Xanthi FC.He resigned in December 2006 and, later that month, signed a six months contract and replaced Trond Sollied as the head coach of Olympiakos.Although Olympiacos was eventually crowned champion, the loss of the derby of the eternal enemies, the disqualification by a lower division club in the Greek Cup and the loss of Rivaldo led Olympiacos fans to boo Lemonis, Sokratis Kokkalis (the chairman of the club) and the players.
