It's one of the oldest running jokes in the Premier League over recent years, and frankly Manchester City fans are getting sick of it.
Every time they play at home, and every time empty seats are spotted on television, the word 'Emptihad' seems to make an appearance.
While it's true there are plenty of seats still available for the club's Champions League return match at home to Dynamo Kiev, there's surely an explanation for the swathes of sky blue we often see when Manuel Pellegrini's team play at the Etihad Stadium.
There must be a reason for it all, we thought, so we tried to get the answer straight from the horse's mouth.

While it would have probably been excusable for City fans to go off on one, they're clearly a reasonable bunch based on our interactions.
Here are a few of the explanations given for a phenomenon they'd surely rather do without.
The attendances for league games are regularly above 50,000, which isn't at all bad for a stadium which holds little more than that

So it could well be an issue which affects plenty of clubs, from the top to the bottom of the Premier League

One scenario which isn't common throughout the league concerns the family section, and plenty of supporters mentioned this to us

There's also a chance that the timing of the Kiev tie has played a part

There's one final theory which we hadn't considered, and who knows, there could be something to it
