The Three Lions were beaten 2-1 on Wednesday night after an extra-time strike from Mario Mandzukic secured Croatia's spot in the final, where they will face France on Sunday. We're gutted, we've worked so hard and the fans were incredible.
Croatia's World Cup final opponents, France, are associated with the words "formidable" and "dramatic" as well as "lucky".
Laura Grimes, of Cambridge University Press, said: "The huge amount of language data we've collected and analysed gives us fascinating insight into the mood surrounding the World Cup".
While we didn't see Southgate plop down on the field to mourn the loss like some of his players did, photographers did capture an extremely touching post-game moment he shared with his wife Alison in the stands.
The victory ensured Croatia reached the World Cup final for the first time, where they will take on France on Sunday in a repeat of the 1998 semi-final.
This is an England team which has inspired a level of belief and excitement among the country's population which hasn't been seen in more than 20 years, and it has not gone unnoticed among the squad.
"It's hard to put that into context now, and a bit too soon".
"I think that's maybe something for a couple of days time, at the moment we all feel the pain of this defeat", he told reporters.
"I can't go back for the final though, I've used up all my credits with my wife".
Captain Harry Kane tweeted: "It hurts a lot".
"I really didn't understand these questions, always looking back to where I made some mistakes".
"We were not creative enough, having just two efforts on target, and in the second half England were overrun in midfield by Modric and Rakitic".
"Tonight was a wonderful opportunity for us and you can't guarantee that those opportunities will come again", he added.
It's the second time the two teams have met at the tournament and the second time that the outcome of their match will be relatively inconsequential.
