Chinese stadium builder Lander has been in protracted talks to buy Southampton from current owner Katharina Liebherr since the start of the year, but the deal has hit some road bumps, including Lander's listed unit pulling out of the deal in April.
"It is not clear at the moment. The seller is having second thoughts about selling the club," Lander's founder Gao Jisheng told Reuters on the sidelines of an event in Beijing. He declined to comment further on the deal.
An external PR spokesman for Lander later said Gao had not made the comments as reported.
Southampton was rescued from the brink of bankruptcy by German-born Swiss businessman Markus Liebherr in 2009 and his daughter Katharina inherited the club after his death in 2010, becoming non-executive chairman in 2014.
Although not one of the traditional powerhouses of English football, the club has finished in the top eight of the Premier League for the last four seasons and has a highly-regarded youth development operation.
The Premier League had given Lander's owner Gao clearance to take an 80 percent stake in Southampton's holding company, Lander Sports Development Co Ltd said in June.
With support from Beijing, Chinese investors have ploughed billions of dollars into global soccer teams over the past couple of years.
However, overseas investments have become riskier business this year amid a crackdown by regulators on "irrational" spending overseas, including in sport.
Suning Commerce Group Co Ltd, which bought Italian soccer club Inter Milan last year, saw its shares fall this week after China's state broadcaster cited the 270 million euros ($313.98 million) deal on a show about risky investments.
Beijing is on a drive to control risks in its financial system, including firms taking on excessive levels of debt to fund overseas deals. Chinese authorities clamped down on capital outflows and overseas acquisitions last year.
