Former AC Milan director Ariedo Braida rates Sunday's Derby d'Italia as a title decider.
Inter Milan meet Juventus leading the table.
And Braida told Radio Sportiva: "Nerves are important, it will be a match that will say something.
"Whoever wins will then have crucial mental strength to win the championship, while whoever loses will hardly be able to recover but in football it is always difficult to make predictions: I expect a decisive match.
"Whoever wins will take the Scudetto."
