Xavi has endured a long season with Barcelona but allayed any fears for his fitness.
“I am in very good shape and very pleased, excited and physically fine,” the 32-year-old said.
“Yesterday I trained (with the national team) for the first time, I played the King’s Cup final, and I was already feeling good at Real Betis on the final day of the La Liga season (on May 12).
“I am ready to compete and to make history again with the national team.”
