Alpha Ethniki newcomers Kallithea GS have appointed
Vangelis Vlahos as their third coach of the season.
Former Panahaiki FC coach Vlahos, 40, has signed a contract keeping him at the club until the end of the season, with an extension for a further year.
He replaces Nikos Anastopoulos, who took over at PAS Giannina FC last week, having himself succeeded Nikos Kourbanas, who resigned after defeats in Kallithea's first two games.
Kallithea lie 13th in the 16-team division with five points from their opening seven matches.
