England fans partied into the night to celebrate reaching the World Cup quarter-finals with a comfortable 3-0 win against Senegal yesterday.
Many Brits complained of sore heads as they set off for work after packing pubs to watch the knockout clash, with an estimated 15 million pints expected to have been sunk.
One Twitter user wrote: "Well that was a really good night watching England game, carrying myself into work today with a hangover."
Another posted: "Can confirm that both football and a hangover will be coming home tomorrow."
And a third added: "England v France. My prediction... HANGOVER."
Minutes before the final whistle blew, supporters were chanting "England, England" at Croydon Boxpark in south London.
White confetti was released as the game ended, and fans erupted into loud cheers, jumped together in celebration and punched the air.
Elsewhere, fans at The Eastney Tavern in Southsea, Hampshire, clapped and cheered as the final whistle blew.
After watching the match, regular Mark Ellinor said of England: "I think they have got it in them, they are a really strong side and we have a good chance of winning the whole thing."
Supporters who had made the trip to Qatar said they were "loving every minute" of England's journey in the competition, with one optimistic fan predicting a penalty shootout win in the next round.
Concerns were aired after the game after news emerged that the home of winger Raheem Sterling had been broken into by armed intruders.
The Chelsea forward was absent from the squad following the incident on Saturday evening, leaving him shaken and concerned about the well-being of his children.
Despite a cagey opening 30 minutes against Senegal on Sunday, Liverpool captain Jordan Henderson calmed any England fears.
Harry Kane, who wore an 'Education for All' armband during the clash, then scored a goal on the stroke of half time, which saw beers thrown into the skies at fan parks across the nation.
A composed second-half Bukayo Saka finish rounded off another professional display, prompting a chorus of "football's coming home" at Croydon Boxpark.
Three Lions supporters at the match admitted there were nerves ahead of kick-off, as they were greeted by a carnival atmosphere of dancing Senegalese fans ahead of their crunch World Cup knockout game.
Labour leader Keir Starmer took to Twitter to say next week's quarter-final will be a "huge game", adding: "But is anyone else starting to believe that it might be coming home...?"
England fans Joe Hawkins and Sean Firmin, both aged 30 and from Middlesbrough, arrived in Qatar on Sunday morning, came straight to the Senegal game and have secured tickets for the quarter-final with France.
IT consultant Mr Hawkins, speaking outside the Al Bayt Stadium, said the first 30 minutes against Senegal were "tough going", but felt the two goals before the break helped kill the game.
He said: " Jude Bellingham was the best player on the pitch - outstanding, wasn't he?"
Radiographer Mr Firmin had predicted a 3-0 win against Senegal, adding of France: "I reckon it'll be after extra time, I reckon it might go to penalties and I reckon we'll do it on pens."
Teacher Marie Sibley, 50, who lives in Qatar by way of Shropshire, hailed the "fantastic" result for England after watching her sixth game at the World Cup.
The England fan said: "I'm loving every minute of it."
She added: "It was really stressful but when those first two goals went in I relaxed a bit and the third one that was it, we knew we were going through."
Asked if she was daring to dream, Ms Sibley replied: "Absolutely, my mum and dad have come over from England, so we'd love them to bring it home."
England fan Karen Barham, 60, had admitted to being nervous ahead of the Senegal game but was relieved after the full-time whistle, despite a "very, very uncomfortable" opening 30 minutes.
The solicitor, from Guildford, said she was "relieved. That first 30 minutes I was actually very, very uncomfortable and I was right behind the goal, second row, saying: 'Give us a goal, the stress is killing us', it was horrendous.
"The first 30 minutes was very, very tense and edgy and then (Jordan) Henderson is a quite unlikely goalscorer, but once we got one on the clock and then (Harry) Kane just in that added time before half-time, (Senegal) didn't really do anything after."
Ms Barham said there were "loads of positives", including the clean sheet, adding: "For the people going home tomorrow they're delighted England have got through but it's tinged with that 'oh god, I wish I was staying'.
"For those of us who think 'I should now apply for settled status' here because I'm out for the duration."
Ms Barham said she will have to do some work from her accommodation to keep her clients happy, adding: "In his steady, workmanlike way, Gareth (Southgate) is delivering and so far we've done the job."
