"Gianluca was a wonderful person and leaves an unfillable void, in the national team and in all those who appreciated his extraordinary human qualities," said Italian Football Federation president Gabriele Gravina.

Vialli participated in two World Cups: 1986 in Mexico and 1990 on home soil, where Italy won a bronze medal.

In 1992, he was transferred to Juventus for a then-record 12.5 million Euros, where he won the Italian Cup (he won three), the Serie A, the Italian Supercup, the UEFA Champions League and the UEFA Cup. He was a player-manager for Chelsea in 1998 and 1999 and joined Chelsea on a free transfer in 1996. He managed the club for another year before going to Watford for a year.
