Juventus striker Carlos Tevez has warned AS Roma can still catch them after Sunday's 2-0 defeat to Napoli.

Tevez insists Juve do not have the title wrapped up.

"With Roma there are two clubs fighting for the title," Tevez said.

"Roma are working very well, and are building a team that can look to great things. Mathematically the Giallorossi still have a chance of winning the Scudetto.

"And until we have mathematically won it, we cannot say we are champions."
