Monday's edition of newspaper "i" citing the PGR, reported that Carvalho and another leader of the club (whose name was not disclosed) are both under investigation.

"The suspected crimes are of influence peddling, and no defendants have yet been identified," the newspaper reported, noting that "the investigation is being conducted by the Department of Criminal Investigation and Action in Lisbon," and no final report has been published.

In 2017 Carvalho was also investigated by the authorities following an anonymous complaint about "alleged threats to referees."
