Ahn missed a penalty during the first half of Korea's 2-1 win over Italy on Tuesday, but was hailed as a national hero when his 116th-minute header set up a quarter-final with Spain.
Gaucci told Italian sports daily La Gazzetta dello Sport: "That gentleman will never set foot in Perugia again.
"He was a phenomenon only when he played against Italy.
"I am a nationalist and I regard such behaviour not only as an affront to Italian pride but also an offence to a country which two years ago opened its doors to him.
"I have no intention of paying a salary to someone who has ruined Italian soccer
