Barzagli set to miss Confederations Cup?
The Bianconeri star helped guide the club to their second consecutive Scudetto.
However, the 32-year-old has been unable to train regularly due to the reoccurring injury.
With Cesare Prandelli set to name his 23-man squad on Monday, there is growing concern that Barzagli will be left off the team if he unable to show he can return to being 100% fit.
The tournament runs from June 15-30 and sees Italy in Group A with Mexico, Japan and Brazil.
