We know that we’ve got experienced competition and we can’t help but acknowledge the value of our opposition. The title race is open and it’s our duty to believe we can do it.’’Juve’s nearest challengers Napoli stepped up their title challenge with a 1-0 win at Cagliari last weekend. Marek Hamsik scoring the only goal in that match, and the Slovakian has called on his side to continue in the same vein throughout December, starting with Sunday’s home encounter with rock-bottom Pescara.Third-placed Fiorentina are defending an eight-match unbeaten run and will hope to continue exerting pressure on the leaders when they play host to Sampdoria.
