Arsenal defender Calafiori injured on Italy duty

The youngster was forced off in the first half of Italy U21s' friendly against Germany

Arsenal defender Calafiori has been injured while on duty with Italy U21s.

The 19-year-old was forced off in the first half of Italy's friendly against Germany on Thursday.

Calafiori is now a doubt for Arsenal's pre-season tour of the United States, which begins next week.

The injury is a blow to Arsenal, who are already without a number of defenders due to injury.

Calafiori has been one of Arsenal's most impressive young players in recent months.

He made his debut for the first team in the Europa League in December and has since gone on to make four appearances for the Gunners.

Calafiori is a versatile defender who can play at left-back, centre-back and right-back.

He is also a good attacking threat, with a strong left foot.

Calafiori's injury is a reminder of the importance of squad depth.

Arsenal have a number of talented young players but they are still short of experienced options in some positions.

The Gunners will be hoping that Calafiori's injury is not serious and that he will be able to return to action soon.
