Italy defender Fabio Cannavaro believes Juventus may have the upper hand when they face Inter in the Serie due to the abundance of key players at their disposal. "I am not saying that the Bianconeri are favorites, but I would say that Inter have to watch out," the Real Madrid man was quoted as saying by Calcio Italia magazine. "Alessandro Del Piero and Zlatan Ibrahimovic are the key men. But things are in Juve's favour in that if they can stop Ibra. "Inter have few alternatives, while Juve have players like David Trezeguet, Pavel Nedved and Mauro Camoranesi who can change games." Cannavaro played for both sides before moving to the Spanish giants in the summer of 2006. Serie A leaders Inter host Juventus at the San Siro on Saturday. The Nerazzurri are in charge of the league table with 68 points, seven ahead of second-placed Roma.
