Vialli had been reunited with national coach Roberto Mancini, a lifelong friend and strike partner when they both played for Sampdoria, where they were known as "the goal twins," while working with the Italy squad.
Vialli and Mancini led Italy to the Euro 2020 tournament in 2021, collecting the championship in Wembley Stadium, where their Sampdoria squad had lost the European Cup final to Barcelona 29 years before.
They celebrated last year with a tearful embrace that "was more beautiful than the hugs we used to give each other when I passed him the ball and he scored goals," Vialli said in a TV interview with Italy's RAI in November.
