Fans had already started to gather at the Rajamangala Stadium in Thailand to watch the Premier League and Championship sides in action.
But just minutes away from kick-off, the heavens opened above and a heavy downpour engulfed the venue.
While players from both sides trained on the pitch, everyone was immediately soaked and large puddles gathered on the turf.
The ball could not move and Leicester pair Marc Albrighton and Harry Winks, due to play his old side, demonstrated the conditions to the refereer.
They were seen scooping up the water and waving their hands, indicating that the game could not go ahead.

It will be a disappointment to Australian coach Postecoglou, who lost his first game in charge in a 3-2 defeat to West Ham last week.

The Tottenham boss said: "The other night (against West Ham) was for us a good start in terms of at least the players know in terms what it feels like and some of the things we've been working on, they really tried hard to implement.
"It's still very early stages. [On Sunday] with the weather here it'll be a challenge for us to play at high intensity.
"I've been here with Australian teams, and we found it very difficult and I'm sure it will be.
"At the same time, that's how we want to play.
"The players have been really receptive to this so hopefully from [Sunday] we'll see improvement and progress from the first game."
