The Old Lady was linked with a move for Liverpool manager Rafael Benitez in the Sun today.
Blanc said: “I understand the concerns of the fans but we will not make a coaching change.
“We have complete trust in Ranieri, just as the Juve president said on Sunday. I can confirm that 100 per cent.
“With Ranieri, with his coaching staff, with the medical staff we will analyse the situation in order to find solutions to see Juve return to be the team we saw at the end of August.
“Juventus have the capacity, the history, the inner strength to come out and continue a project that will make our fans proud to be Bianconeri supporters.”
