Fellow fan Alex Klein, 28, added: "If we win, if we beat Croatia I'll, I'll probably cry, because to see England in a World Cup final is, is like a dream, a lifelong dream".
Three minutes into the game, they secured a free kick just outside the box.
Football was all set to come home.
"We're gutted", said Kane, who still on course to finish as the tournament's top goalscorer with six strikes in Russian Federation, told ITV.

When heartbroken English fans wake up Thursday morning after a long night of crying into their pints, the most hard part of their grief to digest following the Three Lions' 2-1 extra-time loss to Croatia in the World Cup semifinals Wednesday in Moscow will be the unshakable feeling that England had this one in the bag.More news: Sagan Wins Stage Two at Tour de France, Dons Yellow Jersey

The Croats needed extra-time and penalties for the second successive knockout game, beating Russian Federation last time, so it wouldn't be a surprise to see them tire at some point in this game.
Had Kane added to his six goals in Russian Federation with either of his back-to-back chances in the first half against Croatia on Wednesday, when England was dominating and led 1-0, he could yet be lifting the trophy on Sunday.
"Anyone want a World Cup Final ticket", he asked in another post. "We felt we were good enough but have fallen just a bit short". "You brought us all together and made us very #proud".
"I don't know what will happen if we win, probably nobody will go to work. But we have our hearts, our pride and our players and that is what is really important to us".
After watching their team stumble at major tournaments for decades, often falling to much smaller nations, England supporters had begun to think that 2018 might be a different story.
Phillip Schofield praised the team for what they had achieved and for uniting people. "For us, it was impressive to watch a team such as the English, that is so strong physically, and they couldn't keep up anymore, and we did have that energy".
