The defensive midfielder, the younger brother of Arsenal centre-back Kolo Toure, will not be leaving Camp Nou.
"Yaya Toure will not be leaving," said a Barcelona spokesman.
"He is an important player for the team and it does not enter our plans to sell him."
New coach Pep Guardiola is also adamant that the 25-year-old features in his long-term plans.
"Yaya is a key man in my scheme," added Guardiola.
