The Three Lions are two wins away from getting their hands on the World Cup trophy for the first time since 1966, and Southgate's men are, so far, exceeding their own expectations at this summer's tournament in Russian Federation.
But as he conducted his pre-match press conference, football was not the only topic after cameras had captured the players throwing a rubber chicken to each other during their warm-up.
Millions are expected to flood into England's pubs tonight in the hope of finding the most electric atmosphere to watch the game.
Just the small matter of a game in which Croatia stand between Southgate and his ambition of matching Sir Alf Ramsey's feat of taking England to the World Cup final.
"Whether we win or lose, we're creating history", he said.
"I think there'll be a bit of nerves as the day comes but a bit of excitement as well because you know you've always dreamed of playing in a World Cup final".
"Our supporters and our country has had a long time suffering in terms of football".
Dalic: Croatia will have enough energy for England
But ever since the group stage, when they upset Argentina, Croatia have failed to turn on the style. "Well done Croatia . England had never overachieved, but this team have in reaching the semifinal.
The song, recorded by David Baddiel, Frank Skinner and the Lightning Seeds, has been echoing around the nation once again ever since it became apparent that Southgate and his team were going to have an extended stay in Russian Federation. Football might actually be coming home after all.
"Gareth, good luck. Stick to what you're doing, I'm behind you", he added.
But Southgate revealed he could not listen to it for many years.
In case, England goes on to win the match, Croatian stores in the United Kingdom, if there are any, may need to be wary of overenthusiastic fans.
Southgate was a key player for England at Euro 96 but saw his penalty saved in the shoot-out at the end of the semi-final against Germany which saw them knocked out. "It's up to us now which games we play in".
"The welcome of the Russian people has been top", Southgate said. Everyone has been out on the streets celebrating what we've achieved and that is a great source of pride for us. "We're not working much now so you can imagine what it will be like if we win".
