1980s
Lazio were forcibly relegated to Serie B in 1980 due to a remarkable scandal concerning illegal bets on their own matches, along with Milan. They remained in Italy's second division for three seasons in what would mark the darkest period in Lazio's history. They would return in 1983 and manage a last-day escape from relegation the following season. 1984-85 would prove harrowing, with a pitiful 15 points and bottom place finish despite the emergence of promising, though albeit unfulfilled talent of Francesco Dell'Anno and Francesco Fonte.
In 1986, Lazio was hit with a 9-point deduction (a true deathblow back in the day of the two-point win) for a betting scandal involving one player, Claudio Vinazzini. An epic struggle against relegation followed the same season in Serie B, with the club led by trainer Eugenio Fascetti only avoiding relegation to the Serie C after play-off wins over Taranto and Campobasso. This would prove a turning point in the club's history, with Lazio returning to Serie A in 1988 and, under the careful financial management of Gianmarco Calleri, the consolidation of the club's position as a solid top-flight club.
