Griezmann was dropped for the midweek clash against Real Valladolid with Ansu Fati taking his place in the line-up, and Valverde says the Frenchman's spot isn't necessarily a given.
"He is a player who has been playing regularly.
"The other day I made some changes.
"I don't like to talk about indisputable starters.
"He will play if he meets his requirements."
