Sassuolo striker Simone Zaza and Juventus defender Andrea Barzagli have left Italy's squad ahead of Friday's Euro 2016 qualifier against Croatia due to a lack of fitness, the Italian football federation (FIGC) said Monday.

Both players had been called up to Antonio Conte's 28-man squad for the qualifier in Split, Croatia as well as a friendly against Portugal in Geneva next Tuesday.

However Zaza had already complained of a sore back prior to travelling to Coverciano, and Barzagli, who only returned to training last week after suffering an injury knock, has not fully recovered from playing a full 90 minutes in the Champions League final against Barcelona on Saturday.

A FIGC statement said: "The Juventus defender Barzagli and the Sassuolo striker Zaza have left the training camp due to lack of fitness."

Italy, second in Group H two points behind leaders Croatia, face Niko Kovac's side on June 12 at the Poljud stadium looking for their fourth win in five qualifying matches.

A win for Croatia would see them pull five points ahead of Italy and leave Conte's men in danger of being overtaken by Norway, who are only two points adrift ahead of their home game against Azerbaijan.
