Spain's decision to invite Pedri to the Olympics after the Euro 2020 match has annoyed Barcelona coach Ronald Koeman.
The Dutch boss believes that the young star of his team needed more rest.
Koeman told a media conference:
"Pedri has played a lot. We will have to give him a break, everyone needs it during the [European] summer
"As Pep Guardiola said, playing two important tournaments in the summer is too much, but we can't do anything.
"Pedri's European Championship was phenomenal. At the age of 18 he has played almost all the complete matches, with an impressive maturity.
"His football continues to improve and he is a very honest and calm boy. He lives for football. He is an example of how to be a young man at Barca.
"It is important for our grassroots football, that young people see that they are in a club that gives them opportunities."
Eric Garcia is also in Spain's squad for the tournament, who re-joined Barça with a free transfer from Manchester City. Koeman believes the 20-year-old former Barça academy player could have a big impact on the team.
He has had a great European Championship
," Koeman said.
"He comes from here and, despite his youth, he already has a lot of experience. He plays in the same position I did.
"With the ball he is very good and we can improve from behind with him. He also has projection and a great future ahead."
