Sampdoria midfielder Ronaldo Vieira was subjected to racist chants by Roma fans during the teams' 0-0 draw but Serie A's sporting judge said on Tuesday that he has asked for more information before deciding on a possible punishment.

Roma has already said it "will support the authorities in identifying and subsequently banning any individuals found guilty of racially abusing the midfielder."

Vieira, who was born in Guinea Bissau, plays for England's Under-21 team.

Offensive chants have also been aimed at Romelu Lukaku, Franck Kessie, Dalbert Henrique and Miralem Pjanic in Serie A games this season.

The Italian soccer federation is said to considering employing advanced listening devices used in anti-terrorism operations to identify offending fans
