The former Italy midfielder expects the outcome of the Derby della Madonnina to prove decisive in the Scudetto chase, and remains confident the Nerazzurri will be fired up
The Rossoneri go into the clash just a solitary point behind Juventus with two games to go, and a win against their arch-rivals at San Siro coupled with a negative result for the Bianconeri could see the champions move to the summit.
However, according to the Milan great, his former side will face a difficult test against Inter as he dismissed the impact of the Nerazzurri's 3-1 defeat to Parma on Wednesday, claiming their pursuit of a Champions League qualifying place is still within their grasp.
"The derby will decide the league championship, so as a result it is impossible to tell who is at an advantage in games like this," Rivera told La Gazzetta dello Sport.
"Inter's defeat should not diminish their motivation. Juve and AC Milan go into the end of the season with the same charge, even if Milan had remained three points behind."
Kick-off between the Milanese giants is scheduled at 20.45CET.
