A strange fact happen while we have official statements from Manchester we have nothing from the Juventus side, don't you think is strange?
Juventus may prepare to announce it after everything is ready first.
Actually, Allegri implicitly already told us that Ronaldo left Juventus. It is shown on Juventus official Twitter. He stated that Juventus lineup will have no Ronaldo on the next match. Allegri is confident it is not a problem to have no Ronaldo, there are many other players who can score as well as Ronaldo. So, it indicates that Juventus decide to not rely on Ronaldo anymore.
