Juventus coach Massimiliano Allegri has warned his side that they are not yet champions, despite the 3-0 win over Lazio on Wednesday night restoring their nine-point lead with four games to go.
The Bianconeri travel to Fiorentina on Sunday knowing victory will all but seal the title, but Allegri says the champagne will remain on ice until second-placed Napoli no longer have any chance of catching them.
Should Juve take three points in their fixture, then Napoli will have to win at Roma on Monday to keep the title race alive.
"Napoli could potentially win all of their remaining games and we need four points to be absolutely certain of winning the Scudetto," he told Juventus' official website. "We need to get three [points] away in Florence where we want to put in a great performance, but it won't be easy.
"Then I don't mind if we celebrate winning the title in front of the TV [watching Napoli]."
Few expected to see Juve in such a commanding position after they made one of their worst-ever starts to a season. They recovered from that to go on a run of 23 wins in their last 24 games -- the other a draw -- to pass Napoli at the top of the table.
Without such a poor start to the campaign, Juve could now be setting new Serie A records, and Allegri is hoping his team continues their outstanding form through into next season.
"We've grown a lot but we can and we must continue to develop. Hopefully next year we can start better off in the league," he said. "This group came together this season and has improved game by game, so it's now important to conclude the campaign in the best possible fashion and then to think to the future.
"We've got to do better in the Champions League. It was hard to digest this year. We got knocked out this year on the final cross of the game [against Bayern Munich], but we need to do better next year."
