Toni's third season with the club was less successful, as injuries and clashes with the club's manager Luigi Delneri saw him struggle to gain form and playing time. After Verona was seen relegated from the 2015–16 Serie A season, Toni confirmed his retirement from football on 4 May 2016. He scored his last ever career goal on his final match from the penalty spot in a 2–1 home win over Serie A champions Juventus, with a Panenka style penalty, and later also started the play which led to Verona's second goal; this was his 23rd appearance and sixth goal of the league season. In the 85th minute, a visibly emotional Toni was substituted and received a standing ovation from the fans. In total, he had managed 48 league goals for Verona during his three seasons in the Italian top division with the club, 157 career Serie A goals in 344 league appearances, and a career total of 324 goals in all competitions (with 659 appearances and 306 goals at club level, and 47 appearances and 16 goals with the Italian national team). Toni explained his decision to retire after the match, stating that he would not be playing in Verona's final match of the season, in an away fixture against his former club Palermo, as he wanted to play his final career match in his team's home stadium.
