playing Danilo at RW or LB is quite a stretch
The guy was RB by trade at America and then at Santos, especially since the arrival of Jonathan, has been playing primarily at left or right mezzala ... even Para is their back-up RB, from what I have seen.
Putting him on as a pure winger or central mid would be suitable only for emergencies, I think ... and sort of an experiment too.
I am still pretty perplexed as to how Juve think of using Danilo considering all your transfers and rumours point towards Conte using a version of 4-4-2. Not sure Juve should be focusing on getting a 10+ mil 19/20 yo player as a back up RB or a 2nd and even 3rd string emergency RW when they need to build a new backbone for the team and should only then start worrying about investing in young alternatives/up-and-comers ... which would be a good thing to do once the team is back in the CL.
Going for Danilo would have made sense if Licht hadn't been bought already or Conte was going for a 4-3-3, which doesn;t seem like the formation he would go with, at least at first.
I still think this is a random transfer on the side of Marotta probably looking to get rid of the image of a guy thinking inside the box only and not looking outside Italy for reinforcements.
