GLMS president Ludovico Calvi warned that given the financial impact of the novel coronavirus (Covid-19) pandemic, match-fixing may become a greater threat than before due to the increasing power of the financial incentives.
“Additional threats are likely to continue to materialize while sport events resume in a usually quiet sporting period of the year, given that the financial crisis has adversely impacted countless sport organisations globally, which in turn, may increase the level of risk-taking and vulnerability of athletes and sport stakeholders,” Calvi warned.
