Zlatan Ibrahimovic is to be investigated by Uefa over an “alleged financial interest in a betting company”.
Uefa’s disciplinary regulations state players should not have a financial interest in betting.
Last week he signed a new contract that will run until after his 40th birthday.
“A Uefa ethics and disciplinary inspector has today been appointed to conduct a disciplinary investigation regarding a potential violation of the Uefa disciplinary regulations by Mr Zlatan Ibrahimovic for having an alleged financial interest in a betting company,” a Uefa statement said.
The former Manchester United striker has scored 17 goals in 25 appearances in all competitions this season.
Ibrahimovic came out of international retirement after a five-year absence to play for Sweden earlier this year.
