[1] Galeone started his coaching career at 34 for Serie D team Pordenone, in 1975–76, obtaining an eleventh place in his debut season.
He left Pescara in 1988–89, after having failed to avoid relegation for his second time, but returned in 1990–91 and regained promotion to Serie A in 1991–92.
In 2006, Galeone made his comeback at Udinese, as he was called to replace Loris Dominissini and Néstor Sensini at the helm of the bianconeri.
Galeone is well known for being a strong advocate for the 4–3–3 formation, zonal marking, and an attacking style of playing, which made of him one of the most innovative Italian football coaches in the late 1980s alongside Arrigo Sacchi.
On 19 July 2007, he was announced to make a fourth comeback at Pescara, this time as technical consultant beside new boss Andrea Camplone, a former player of his in the 1990s,[2] but left the club only one month later.
