Russia coach Fabio Capello sees AS Roma as the biggest threat to Juventus' claims on the Scudetto.
Capello has managed both clubs during his career.
"Roma are the only anti-Juventus side out there,” insisted Capello despite a 12-point gap.
“The Bianconeri are doing very well, even if they haven’t got challengers up to the task. In my day in Turin, we had Milan, Inter and Roma. Now the Milanese clubs have sold many important players.”
