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.
