Barcelona have been dealt a massive blow ahead of the 2019/20 La Liga campaign after Lionel Messi limped out of his first training session with a calf injury.

The club confirmed the Argentine icon will not join the rest of his team-mates on their tour of the USA after suffering a Grade 1 calf strain on Monday.

Ernesto Valverde and his contingent are travelling to Miami for a double-header against Italian giants Napoli.

Messi had only just returned to training from his extended summer break following Copa America efforts with Argentina.

Although a timescale for his return was not confirmed, the lack of training and the time out will now likely mean Messi is a doubt for Barca’s curtain raiser at Athletic Bilbao on Friday August 16.
