AEK Athens midfielder Giorgos Katidis has been condemned by politicians, fellow sports personalities and fans after giving a Nazi salute to celebrate a goal he scored in the Greek league.
Photographs show him giving the salute after scoring the go-ahead goal in the 84th minute over visiting Veria this weekend.
In one photo, Katidis' Brazilian-born teammate Roger Guerreiro looks at him with an expression of astonishment.
Katidis, 20, pleaded ignorance of the meaning of his gesture - right arm extended and hand straightened - and claimed on his Twitter account that he detested fascism.
AEK's German coach Ewald Lienen said the player did not have an "idea about politics".
