England fans were left fuming as BBC iPlayer went down minutes before the end of the Three Lions' crunch game with Sweden.
Viewers said the streaming service, funded by the licence fee, cut off with just a few minutes left of the match against Sweden, which England won 2-0.

Craig Errington tweeted: "Did BBC iPlayer suddenly go offline for anyone else? Missing the last few mins of England game."
David Carr added: "iPlayer goes down with three minutes to go…
"BBC I want a full refund of my licence fee and a restaurant voucher minimum as compo #fuming."
Others were not impressed with the BBC iPlayer Twitter account tweeting: "It's coming home."
Jeremy Mortimer replied: "We wouldn't know – iPlayer crashed for most of us with three minutes to go…"
Ihab El-Alami added: "Annoyed as those last three minutes and celebration after missed from eternal memory."
"Fix it! What a way to ruin the biggest moment so far in 28 years," Mark Wendl said.
Wimbledon fan Alex Shorey added: "@BBCiPlayer what the hell wrong with iplayer will not work since the match ended.
