Italy players Alessandro del Piero and Gianluca Zambrotta have left the team’s World Cup camp in Germany to visit Juventus colleague Gianluca Pessotto.
Juventus sporting director Pessotto is seriously ill in hospital after falling from a window at club headquarters.
Del Piero and Zambrotta were joined by ex-Juventus player Ciro Ferrara, one of Italy’s coaching staff.
Pessotto, 35, was recently appointed Juve’s sports director after 11 years as a player, during which he won 22 caps for Italy.
Italy captain and Juventus defender Fabio Cannavaro walked out of a media conference when he heard about Pessotto’s fall.
“I’m devastated. Pessotto was the nicest guy in the world,” said Cannavaro.
Pessotto’s wife Reana said he was unhappy with his role at the club and had been suffering from depression.
“He kept telling me that there was too much difference between being on the field and behind a desk,” she said.
A hospital official speaking on Sky Italia television said police were investigating a suicide attempt.
A Juventus spokesman said: “Gianluca suffered multiple fractures, but his life is not in danger.”
