In 1986, he joined Milan (1986–87), and later played for Lazio (1987–88), and also had a second spell with Verona (1988–89), although he failed to replicate his form from previous seasons due to several injuries.
[4] As part of this process, on 5 February 1996, Galderisi, along with Jim St. Andre, were allocated by Major League Soccer to the New England Revolution for the team's inaugural season.
[4] Galderisi became the Revolution's second-highest paid player upon signing, making a reported $325,000, including bonuses that were guaranteed, and taking up one of the league's maximum $175,000 salary cap slots.
"[7] Despite high-praise and early hopes, Galderisi struggled to make an impact, ultimately becoming the focal point of the Revolution's first-ever star player controversy and being labeled a "flop.
"[7] He made his Revolution debut as an 89th-minute substitute for Beto Naveda in the club's first-ever match, a 3–2 loss to the Tampa Bay Mutiny on 13 April.
[8] The following week, Galderisi was substituted in the 65th minute of the Revolution's 2–1 loss to the San Jose Clash, and made his frustrations regarding the decision known on the sideline, throwing a "temper tantrum" and stating post-match that management had no faith in him.
He made his international debut on 2 June 1985, in a 1–1 draw against Mexico, and was later part of his nation's 1986 FIFA World Cup squad under manager Enzo Bearzot.
[1][2][13] A quick, agile and diminutive striker, Galderisi was a prolific goalscorer, with excellent reactions who was also known for his work-rate, generosity, tenacity, and his powerful and accurate striking ability with either foot.
Although he began his career as a second striker, he came into his own as an out-and-out centre-forward, due to his pace, eye for goal, and his determined and opportunistic style of play.
In July 2008 he was appointed as new manager of Lega Pro Prima Divisione side Pescara, replacing Franco Lerda, with the aim to win promotion to Serie B for the biancazzurri.
Results did not improve anyway, with Pescara struggling in the bottom part of the table, and Galderisi was dismissed from his coaching post on 23 March 2009, being replaced by another former Juventus and Italy international footballer, Antonello Cuccureddu.
Later in January 2014, he was named the new head coach of Portuguese top-flight strugglers S.C. Olhanense, a club owned by an Italian consortium and with a squad featuring several players formerly of Serie A.
He returned to management in November 2014 to take over at struggling Lega Pro team Lucchese,[19] not being confirmed for the following season despite succeeding in saving them from relegation.
