England's Football Association has been hit with four UEFA charges after trouble at the Euro 2020 final, and a separate investigation has been launched into chaotic events involving supporters at Wembley.
On Tuesday, UEFA said an ethics and disciplinary inspector has been appointed to look into events. There were major disturbances at the stadium on the day of England's big match against Italy.
England lost the final on penalties, after 120 minutes of action ended with the contest level at 1-1.
Damage was caused prior to the match as a number of supporters were seen clashing with security as they tried to enter the stadium in north London without tickets.
The inspector will be tasked with conducting "a disciplinary investigation into events involving supporters which occurred inside and around the stadium".
UEFA confirmed it has forwarded initial charges relating to England supporters to its control, ethics and disciplinary body.
The FA faces possible sanctions over an invasion of the field of play, throwing of objects, disturbances during the national anthem and lighting of a firework.
A UEFA statement read: "Disciplinary proceedings have been opened following the UEFA Euro 2020 final match between the national teams of Italy and England, played on 11 July at Wembley Stadium, London."
After listing the charges brought against the FA, the statement added: "The case will be dealt with by the UEFA control, ethics and disciplinary body [CEDB] in due course."
UEFA previously charged England relating to their semi-final in the tournament after a laser pointer was directed at Denmark keeper Kasper Schmeichel prior to a penalty for the hosts, fining the FA €30,000 (£25,600) for three offences stemming from that game.
