What odds are Panama to win the World Cup?
1,000/1
Who's the coach?
Hernan Gomez has been in charge since 2014. He had to resign his position as Colombia coach in 2011 after assaulting a woman outside a bar in Bogota.
Who's the star?
Not many to speak of. Striker Gabriel Torres, who made his international debut aged 16, has pace and attracted the interest of Manchester United... 11 years ago.
Best thing about them
They're just happy to be here. This is their first ever World Cup so expect the fans to make the most of the experience.
Worst thing about them
They're not very good. Panama will have the oldest squad at the World Cup and will be physical and ultra-defensive: their 5-4-1 formation will occasionally look like a 9-0-1.
You may recognise...
Good luck with that. Unless you're an avid follower of MLS, the home of a decent chunk of the squad, these will be very unfamiliar faces.
Cameramen will be picking out...
Red-shirted fans blubbing their way through the national anthem when it is played for the first time at a World Cup.

On-field prediction
Initially charming story will be swiftly forgotten when Eden Hazard is booted into the stands after 47secs of their opening game against Belgium.
Off-field prediction
Commentators trying, and failing, to shoehorn a canal metaphor into their analysis.
