no.
actually that is wahat you and ur marotta dick sucking bias thinks
what is closer to the truth is that sandro most likely wanted to make sure that the club that put him on the scene gets paid, leaving a club on a free specially after they propulsed ur career is a serius yahudi move (sorry ma jeuw homebois) and sandro has more integrity than that. So he decided to leave on the last season of his contract and let porto take care of business and so they did. juve bought sandro at a price that porto thought was appropirate which was of course expensive and juve paid. simple as that.
