I've never seen anything from Bonucci or Alex Sandro to suggest they want to leave, quite the opposite, so it doesn't concern me at this point. End of the day players change teams all the time, but I don't see it with these two at this point.
The media always stir things up worst when players are off on international duty, they are away from their clubs and these guys think they are soft targets who they can press. It's the time of the year where fuck all is happening so they have to make things happen. I'd like to see the ratio of actual transfers to "solid" rumours, I bet it's not even 5%.
I'm not going to pretend there is nothing in it because football is unreadable now, but probability is in our favour.
