Verona, May 4 - Luca Toni, the big front man who led the line in Italy's 2006 World Cup triumph, on Wednesday said he was hanging up his boots at the age of 38. The tall, gangly striker, last of a breed of Italian 'torri' or 'towers' who were deadly in the air and not bad with their feet, is leaving after his toughest season with a string of injuries and club Verona relegated from Serie A. Having scored 323 goals in a career that took him to 12 Serie A clubs including Palermo, Fiorentina and briefly Roma, Toni has been top goalscorer in the top flight twice and once in the second division. At a club level he won his biggest trophies at Bayern Munich with a League Cup, a German Cup and the Bundesliga title. At Verona he scored 50 goals in the league and the Italian Cup, becoming the oldest player ever to top the Serie A goalscorers' standings - and the first to get there for Verona.
