Orrico started his coaching career by serving as head in a number of minor division clubs in his native Tuscany, and he gained popularity after guiding Lucchese to impressive results in the Italian Serie B, narrowly missing a historic promotion in the top-flight; such results led Internazionale chairman Ernesto Pellegrini to appoint him as new head coach for the 1991–92 season as a replacement for Giovanni Trapattoni, who had just won the scudetto with the nerazzurri side. One of his first moves was to assign the #5 shirt to German captain Lothar Matthäus, instead of his usual #8. However, his career at Inter turned out to be extremely unsatisfactory and he was sacked after a few games in the national league and a disappointing UEFA Cup campaign, ended with an early elimination by Boavista FC. His position was taken by Luis Suárez.
He then coached with little success a number of minor league teams, mostly from his native Tuscany. In 2008 he marked his football comeback, accepting an offer from Serie C2 team Prato. He left Carrarese in June 2009, after his son committed suicide; his dead body was found by Corrado Orrico himself.
