Alessandro Del Piero's Euro 2008 [Images] hopes suffered a fresh blow on Saturday when Italy [Images] coach Roberto Donadoni left the striker out of his squad for Wednesday's friendly in Spain.

The 33-year-old Juventus captain has not played for the world champions since his poor performance in a goalless Euro 2008 qualifier against France [Images] in September when Donadoni used him out of position on the wing.

Donadoni's 21-man squad for Italy's penultimate test before the Euro finals contained no major surprises.

Striker Marco Borriello kept his place after making his debut in February's 3-1 friendly win over Portugal.

Borriello, who has scored 17 league goals for Genoa this season, is expected to understudy Bayern Munich's Luca Toni in Austria and Switzerland [Images] in June.

Inter Milan defender Marco Materazzi is in line to make his first appearance for Italy since injuring his thigh in the 3-1 friendly defeat in Hungary in August.

He was called up for the Portugal game but had to pull out with a back problem.

Sampdoria forward Antonio Cassano seems to have blown his chances by picking up a five-match ban for verbally abusing a referee in a recent Serie A game, the latest in a series of incidents of indiscipline.

Forward Alberto Gilardino, like Del Piero a member of Italy's World Cup winning squad, also looks to have fallen out of contention after a disappointing season with AC Milan.

Italy host Belgium in Florence on May 30 in their final Euro 2008 warmup.
