Lazio were set to play Genoa in an end-of-season final but the match could not be played due to the First World War.
Genoa were regarded as the better side and were awarded the title, but after a fans' petition Lazio may me crowned joint winners of the title.
Lazio president Claudio Loito said: "It is a legitimate Scudetto. It was taken away from us by the war".
The Italian Football Federation will decide on 4 August whether Lazio will be awarded the title.
