The Italian championship could be decided by a play-off should two teams finish level on points in Serie A.
This was after the governing FIGC approved the tiebreaker method at a meeting in Rome on Wednesday.
A playoff will take place should two teams be equal on points, rather than previous tiebreakers such as goal difference or head-to-head record.
Should the playoff be level after 90 minutes, a penalty shootout —- without extra-time —- will decide the destination of the title.
