Spain head coach Julen Lopetegui believes Isco is already among the world's best players as he lauded the Real Madrid midfielder.
The 25-year-old produced a fine display in a 5-0 friendly win over Costa Rica on Saturday before coming off with an injury in the second half.
Lopetegui was delighted with what he saw from the Madrid star, and believes there is even better to come.
"Isco is a player that is already settled in football's elite," he told a news conference. "I say he's settled because he's really constant at a maximum level and that's really hard to achieve.
