Napoli missed the chance to win Serie A for the first time in 33 years on Sunday after being held to a 1-1 draw by Salernitana.
Runaway league leaders Napoli needed to win to secure their third league crown with six games remaining in the season after Inter Milan beat closest challengers Lazio 3-1 earlier in the day.
But the long-awaited Scudetto party will have to be put on hold for at least a few more days after Boulaye Dia's stunning strike six minutes from time ensured Salernitana escaped with a point after Mathias Olivera had headed the hosts ahead just after the hour mark.
However the coming midweek round of matches could finally end Napoli's long wait for glory.
Luciano Spalletti's team are 18 points ahead of Lazio but Juve can close that gap to 17 by winning at Bologna in Sunday's late match and moving into second place.
Depending how that match and Juve and Lazio's games on Wednesday go Napoli could be crowned champions before they take the field at Udinese on Thursday night.
A win in Udine will ensure Napoli's current stars emulate Diego Maradona, who led southern Italy's biggest club to their only previous league titles in 1987 and 1990.
Inter win
Earlier during the day, Inter came back from a goal down at half-time at the San Siro thanks to a Lautaro Martinez brace and another strike from Robin Gosens. Inter's goals all came in the final 13 minutes and moved Inter into Serie A's Champions League places, ahead of AC Milan and Roma on goal difference.
With 26 minutes gone at the San Siro, Inter's Henrikh Mkhitaryan rolled in Joaquin Correa's low pass, only for the strike to be ruled out because Argentine attacker Correa was offside before receiving Marcelo Brozovic's through ball.
Three minutes later Anderson silenced fans both in Milan and Naples with his fine low finish for the visitors after ex-Lazio defender Francesco Acerbi gifted the ball to his former teammates on the edge of the penalty area.
Inter pushed for the leveller, with Nicolo Barella lashing a volley just wide in the 40th minute, but Lazio were unlucky not to be two ahead at break.
Acerbi again lost the ball in a dangerous position and Ciro Immobile's low curling shot was pushed away by Andre Onana to Anderson, whose finish was deflected over the bar by Alessandro Bastoni.
Federico Dimarco forced a fine save from Lazio's Ivan Provedel on the hour mark and moments later Inter's Denzel Dumfries shanked his finish when trying to force home an inviting cross from Romelu Lukaku.
Lautaro Martinez missed a brilliant chance when clean through on goal in the 71st minute but six minutes later made up for his error when he finished low past Provedel.
A huge cheer erupted in the stands in Naples after news of Martinez's equaliser filtered through and the noise levels nearly took the roof off after Gosens forced home Lukaku's cross with seven minutes remaining.
Martinez's second in the final minute put the cherry on the cake for Inter and Napoli, who are ready to claim the title in front of a sea of blue and white.
