Cesc says his former Spain and Barcelona teammate needs to show the world what he can do for Spain in the Euros.
“I think it's time for Thiago to basically do something big in a big tournament. He has been now at the Euros, he has been at the World Cup, he never really played too much.
“So I think he needs to find a consistency to show the whole world that he really has top top level to show it at the biggest stage."
Spain must beat Slovakia on Wednesday to reach the knockout phase of the Euros.
