sport news A pitch in the middle of the sea, seats where the view is more eye-catching ... trends now
Imagine pulling on your kit, getting out your scarves, and trekking to your team's football stadium on a Saturday - only to realise it doesn't exist.
Thanks to the uncanny power of artificial intelligence, we're able to present you with football stadiums that look and feel like they exist, but are in fact just figments of your imagination.
Mail Sport has rounded up images of spectacular stadiums that are real and ones that have been generated by AI to put you to the test.
Six of them actually exist, and six of them are fake.
Can you guess which of these of these grounds are real? The answers are at the bottom.Stadium 1
This modern stadium has some of the most breathtaking surroundings in the world - if it's real
A modern stadium set against the backdrop of spectacular mountains - it's quite a breathtaking view.
This ground looks like it can hold, what 50,000 people? The question is whether they would be real people or just characters in an AI-curated world.Stadium 2
You don't get too many crocodile-shaped stadiums knocking about - would a team actually build a ground inspired by their mascot?
A crocodile-shaped stadium? Surely not.
We're used to teams having mascots and designing them elaborate costumes, but to base a whole stadium off one?
The exterior and background do look pretty convincing, it must be said, although it's hard to tell what country this ground would be based in. Is it real?Stadium 3
An Olympic-style arena which has witness some of sport's greatest triumphs and most cruching failures... or has it?
We've got what looks like an Olympic stadium here, suitable for football or athletics, with a spectacular open exterior.
This amphitheatre has perhaps hosted some of the world's greatest runners, seen records be broke, seen heroes break down in tears and losers despair. Or maybe it has not. You decide.Stadium 4
This is the sort of ground that most of us can actually have aspirations of playing at
We're presented now with a more humble arena, certainly not one accustomed to hosting heaving crowds.
A solitary stand lines half the turf, although it looks like it has fallen into disrepair somewhat. And what's going on with that odd net? Needs a clean up.Stadium 5
English football has its fair share of riverside stadia, but who does this ground belong to?
A glamorous waterfront ground shimmering in the sunlight.
English football is no stranger to riverfront stadia. Take Fulham's Craven Cottage, for instance, or, er, Middlesbrough's ingeniously named 'Riverside Stadium'.
Who could this belong to, though? And does it even exist?Stadium 6
