Luigi "Gigi" Riva, Italy's leading all-time national team goal-scorer, has died aged 79, Italian media reported on Monday.

Riva, whose physical presence and powerful shooting earned him the nickname Rombo di Tuono (thunder-clap), scored 35 goals in 42 appearances for Italy.

Riva had been taken ill at his home in Sardinia over the weekend and treated for a suspected heart problem.

He was part of the Italy team that won the European Championship in 1968 and also played in the 1970 World Cup when they were runners-up to the Brazil team which featured Pele. With his near namesake Gianni Rivera, Riva was one of the poster boys of Italian football then as colour television brought live action to a wider audience. He was a runner-up to Rivera for the Ballon d'Or awarded to Europe's best player in 1969.

Riva played almost his entire club career with Cagliari and was Serie A top scorer when the Sardinian team won the Italian league title for the only time in their history in 1970. He was honorary president of the club at the time of his death.

Injuries marred the latter part of his playing career and forced him to retire in 1976.
