Spezia have been promoted to the Serie A for the first time in their history despite losing the second leg of the Serie B promotion play-off final against Frosinone 1-0.
Friday's (AEST) result at the Stadio Alberto Picco made it 1-1 on aggregate, with Spezia moving up to the top flight due to their superior position in the table at the end of the regular season.
It completes a miraculous recovery for a club that was declared bankrupt following their relegation from Serie B in 2008 and returned the next season in the fourth tier after being re-founded.
Andrea Beghetto hit the post for Frosinone in the 12th minute and Spezia goalkeeper Simone Scuffet made some good saves to keep the scores level at half-time.
Frosinone drew level on aggregate when Marcus Rohden added a fine finish after Andrija Novakovich and Camillo Ciano flicked on a long ball from keeper Francesco Bardi.
The visitors pushed for a winner but were unable to find a way through, with Spezia hanging on to secure a historic promotion.
