Rabbiot will be a great tool for a strong midfield that would compensate for the lack of defesive solidarity as long as Bonucci starts in a two man defense.
Would be great for giving birth to counterattacks with his swift vertical passes, esp under Sarri. So i expect a good impression from him in the first couple of months.
But as the enthusiasm fades away, the pressure will be climbing as we further dcance in the CL and once we lose Ramsey, inevitably from a new injury, we will realize that Rabbiot cannot offer what none of our other CMs/DMs cant either, the offensive build up in the mid line...
