Sergio Aguero will be out up to 10 weeks after suffering a calf injury during Sunday's training session.

Aguero was unable to make his debut in Barca's 3-0 victory over Juventus in the Joan Gamper trophy.

Ronald Koeman described Aguero's injury on Sunday as a "setback."

"It's a pity he got injured and could not play 30 minutes at the Gamper," Koeman said. "It's a setback as he was training and can bring a lot to the team with his quality up front."
