With Manchester City facing a ban from European competition for allegedly misleading UEFA and breaking FFP rules, we've provided a bitesize explanation of the accusations, what they mean, how City have responded and more.

A UEFA panel investigating financial allegations concerning City are expected to recommend the club receive a one-year ban from the Champions League, according to Sky sources.

Here, we get into the who, what, where, when and why of the story...

What are Man City being accused of?

At its core, Man City are accused of misleading UEFA. But the nuts and bolts are more complex.

UEFA have been investigating files, including hacked e-mails - first reported by German publication Der Spiegel last year via Football Leaks - which appear to show City inflating sponsorship income.

These files reportedly include documents and e-mails which show efforts made by City officials to skirt Financial Fair Play (FFP) regulation, by disguising cash infusions from a UAE state-backed investment company as inflated sponsorship agreements, including from Etihad, the club's main sponsor.

For example, a file discovered by Der Spiegel last year suggests that Etihad accounted for just £8m of a £59.5m sponsorship agreement, and the rest was made up from ADUG (Abu Dhabi United Group), the investment group Sheikh Mansour used to buy Manchester City over a decade ago.

What's wrong with that?

UEFA's FFP rules are designed to ensure the amount clubs spend on players and wages is close to what they earn in commercial revenue and prize money.

Simply, they want to ensure clubs do not spend beyond their means, and that financial competition among clubs is kept strong, rather than the richest owners injecting money to blow all rivals out of the water.

So if City's owners were found to be injecting lump sums of cash into the club, this would be a breach of FFP.
