Marco Marchionni says victory for Juventus in the derby against Torino will reignite their Scudetto bid.
The midfielder said: "We know that in the next few days we have two huge games. First there is the Turin derby, it means everything to the city, the club and the fans as well.
"We know if we win on Saturday we can continue to fight for the Scudetto.
"Then there's the return-leg of the Champions League. Having won, Chelsea will be the favourites. By percentages, we have a 30 per cent chance of winning, but we believe."
