The absence of Nemanja Vidic has hit the Serie A side hard and they are easily exposed at the back.
Watching Juan Jesus and Rannochia get far grabbier than necessary in the box and giving the referee far more to think about than he should has become a common feature of their play – and Celtic will be looking to expose that.
They need to get the ball into the box as much as possible and making sure they put pressure on the duo could well see them score a goal or even handed a vital set piece.
