England face being handed a stadium ban by Uefa after the governing body opened an investigation into the chaotic and violent scenes at Wembley around the Euro 2020 final, meaning one or more of their Nations League games next year could be played behind closed doors. The Football Association faces an anxious wait to see what Uefa’s ethics and disciplinary committee makes of what became a disturbingly unruly afternoon on Sunday. Uefa said its investigation would be into “events involving supporters which occurred inside and around the stadium”; it is already understood that hundreds of people without tickets attempted to break through barriers, turnstiles and gates to enter Wembley, and that a significant number succeeded in doing so. Uefa separately charged the FA over fans’ behaviour inside the ground before and during the game, which England lost on penalties against Italy. Those offences were invasion of the pitch, throwing of objects, booing of the Italian national anthem and the lighting of a firework. The FA was fined £25,630 after crowd trouble of a similar nature at the semi-final against Denmark last Wednesday and it will face a heftier bill if found guilty this time. On that occasion a laser pen was shone at the goalkeeper Kasper Schmeichel, the Danish national anthem was booed and fireworks were set off. Although a stadium ban would be at the sharp end of Uefa’s punishment scale, the scenes on Sunday are likely to be looked upon dimly. Should England be forced to play in front of empty stands, they would be required to do so in their next match – or matches – under Uefa’s direct jurisdiction. That means their Fifa-run World Cup qualifiers against Andorra and Hungary this autumn would be unaffected, but games in the 2022-23 Nations League campaign could be at risk. Uefa has shown this summer that it is willing to clamp down on associations whose fans misbehave seriously at venues. This month it ordered Hungary to play two games behind closed doors in Uefa competition, and pay a €100,000 (£85,500) fine, for racist and homophobic abuse during the Euro 2020 group stage.
