I believe Mavropanos was voted the player of the year for West Ham. He was the single reason that they almost avoided relegation. Kouliarakis is 23 and plays for Wolfsberg, rated highly. Retsos has turned aound his career and resembles that guy that secured the then record transfer for a Greek teenager. Don't care for Hatzidiakos. The next guy up would be Mihalidis. Are we world class at the back? No. But Kouliarakis (valued at $25M) and Mavropanos (valued at $18M) are more than capable.
