Karnezis is the one who is playing at the highest level, won the starting job at Udinese over an up and coming GK, won the job at Watford and currently has the job in Napoli (not sure how long that is). Usually consistent outside of penalties.
Kapino has had a rough last year, still has promise.
Paschalakis/Barkas/Giannotis - all three have been solid with Paschalakis standing out because of the first two rounds of CL.
Vlacho - played well for PAO last year and is playing well for Benfica. They really like there, see him being sold for a big fee.
