Reggiana, the third-division Italian soccer team Mike Piazza agreed to purchase in 2016, has been declared bankrupt, according to reports out of Italy.

The team announced on June 24 that it would not be registering in Serie C for the forthcoming season because of its financial issues.

Five days later, the team had begun negotiations with an ownership group led by businessman Pablo Victor Dana, but those negotiations reportedly have ended unsuccessfully, and Reggiana declined to appeal the June 13 ruling that booted it from Serie C. The club, which was founded in 1919, was relegated from Italy’s top flight in 1997 and forced to sell the naming rights of its stadium in subsequent years because of financial woes.

Reggiana would be forced to start in Serie D, Italy’s highest amateur league and a level below, if it bounces back.

Piazza has not responded to The Post’s request for comment.

The former catcher, who starred for the Mets from 1998-2005, arrived last year, full of ambition and hope to turn the club around, and it seemed he was making progress initially.

The number of season-ticket holders more than doubled (to 5,243) after he arrived, and fans respected the the Hall of Famer. As of February 2017, Piazza had traveled to Italy seven times, determined to pull the club up the rungs of the Italian soccer pyramid.

“I’d rather be poor in Italy than based in St. Louis,” Piazza, who had explored MLS expansion franchises, said to the New York Times last year. “You can’t get a good meal there!”

Piazza had also expressed frustration with the way Reggiana was being treated by those in charge of Serie A club Sassuolo, whose stadium Reggiana has had to pay to use since its 1997 relegation.

“I’m tired and sick of Reggiana being pushed around,” Piazza said during a press conference in March. “I am frustrated, and I’m frigging pissed off.”
