UEFA have launched an investigation following reports of monkey chants being aimed at England players.
European football’s governing body had match observers stationed in the stadium for Monday’s clash against Serbia.
And one Serbian fan was allegedly spotted and heard making the chants.
Security did not arrest or remove the fan but Uefa are investigating.
No English players heard the chanting - and the FA have not complained.

There were also claims Serbia fans threw objects while they also displayed inflammatory flags about Kosovo.
This came despite a clear warning that action would be taken.
UEFA said in a statement: "Disciplinary proceedings have been instigated in accordance with Article 55 of the UEFA Disciplinary Regulations (DR) following the UEFA European Championship group stage match between Serbia and England (0-1) played on 16 June 2024 in Gelsenkirchen, Germany."
Charges against Football Association of Serbia (FSS):
- Throwing of objects, Art. 16(2)(b) DR
- Transmitting a provocative message unfit for a sports event, Art. 16(2)(e) DR
- The UEFA Control, Ethics and Disciplinary Body (CEDB) will decide on the matter in due course.
- Furthermore, an UEFA Ethics and Disciplinary Inspector will conduct a disciplinary investigation regarding alleged discriminatory behaviour.
There were major issues in Gelsenkirchen on Sunday because fans complained of long queues outside the stadium and poor stewarding.
