Sordo was born in
Carrara,
Tuscany. He made his professional debuts at not yet 18 with
Torino FC, remaining seven seasons with the club. In
the final of the
1991–92 UEFA Cup, in the dying minutes of the second leg against
AFC Ajax, after a 2–2 draw in Italy, he hit the post in an eventual 0–0 draw (and aggregate loss). In 1993, he appeared in both legs of
Toro's
conquest of the
Coppa Italia, a 5–5 aggregate win over
A.S. Roma. Sordo moved to
Serie A giants
A.C. Milan for
1994–95, being rarely used by
Fabio Capello over the course of two seasons. Subsequently, he did not settle with a team, playing with
A.C. Reggiana 1919,
A.S. Bari and
U.S. Città di Palermo, and also briefly represented
AS Cannes in the
French Ligue 2. Sordo retired from football at the age of 34, most of his last years being spent in the lower leagues. ==International career==
