World Cup 2018: The most bizarre opening ceremony bets on offer
From the brilliant to the bizarre, previous World Cup opening ceremonies have delivered plenty of memorable moments.
From Diana Ross' horrendous penalty miss at the 1994 tournament to the carnival in Brazil four years ago, it's always a guaranteed source of entertainment.
But could we see Robbie Williams dueting with Vladimir Putin this year? The bookies certainly think so.
While the 2018 opening ceremony is tipped to be a much more low-key affair, there will be interest for British viewers with Williams set to headline.
And if the excitement of the former Take That man's presence isn't enough, the bookmakers have a number of interesting bets on offer to add an extra edge to the pre-football festival.
Here's just some of the markets on offer:
What will he sing?
There's plenty of markets available on this front.
Williams' set-list for the ceremony is yet to be confirmed, but you can get odds of 8/11 for him to start with crowd-pleaser Let Me Entertain You.
Rock DJ (7/2) and Party Like a Russian (9/2) are also highly-tipped to be his starting song.
Similar odds can be found for his final song, while it is 66/1 for Williams to end his set with a cover of The Lightning Seeds' Three Lions.
Will he duet?
It could be that Williams isn't alone on stage - with Will Smith the 8/1 favourite to join him in a duet.
An appearance from any member of Take That is ranked as an outside bet at 16/1 with John Barnes (50/1) also an option.
There are even odds for Williams to duet with Vladimir Putin (33/1), Harry Kane (100/1) and Sam Allardyce (250/1).
What about his look?
Markets are available on Williams' outfit, hair and footwear.
He's 3/1 to perform in an England shirt or 33/1 to take to the stage in a full kit.
If he wants to embrace the Russian attire, Williams could don a fur coat (25/1) and ski boots (100/1).
Crocs are an outside footwear bet at 100/1 while it's 33/1 for the singer to rock a patriotic red and white mohican.
