MAN CITY will have to face the consequences, if they are found guilty of breaking over 100 Financial Fairplay rules.

Their Premier League rivals are reportedly calling for them to be relegated, if an independent investigations uncovers any wrongdoing.

While other punishments they could face include fines, points deductions, transfer bans and more.

City fans will be feeling nervous about what awaits them over the next few months.

And if they look at what has happened to other teams, they will be awaiting their fate with bated breath.

SunSport uncovers the most controversial club punishments in football history.

Olympic Marseille

As falls from grace go, this one was spectacular. In 1993, Marseille beat AC Milan to win the European Cup.

However, a year later they were relegated to Ligue 2 after several Valenciennes players claimed they were bribed.

Owner Bernard Tapie went to jail for his involvement, while the club were stripped of their Ligue 1 title win from 1991-92.

Nueva Chicago

The Argie club were embroiled in a relegation playoff with Tigre to save themselves from relegation to second-tier B Nacional in 2007.

At 3-1 down on aggregate in the second leg, their angry fans broke onto the pitch - attacking players from both clubs.

Tigre supporter Marcelo Cejas was struck with a brick lobbed by Chicago thugs, and died from the incident.

Nueva Chicago were deducted 18 points for their following campaign, banned from playing from home, and found themselves relegated again in 2008.

Calciopoli

Juventus were embroiled in the biggest scandal Italian football has ever seen, known as Calciopoli.

It centred around influencing refereeing decisions - and they weren't the only ones, with AC Milan, Fiorentina and Lazio also involved.

Juventus were punished the hardest - and were relegated to Serie B, which they would start their campaign on minus nine points.

The other three had their Serie A status preserved - but were hit with whopping 30-point deductions.

Juventus again

And you would think they would try and keep their noses clean.

This season, Juventus were accused of potentially inflating player values to balance the club's books when carrying out transfers.

They were slapped with a 15-point deduction, which has sent them spiralling out of the Champions League places and into mid-table.

What knock-on effect that has for next season remains to be seen.

Rangers

History counted for nothing when Scottish giants Rangers were in financial ruin in 2011-12.

The Daily Record revealed they were corporately restructured and a new holding company was placed in charge, but it was too little too late.

A vote by the Scottish Premier League members condemned Rangers to the third tier - a spectacular fall from grace.

Luton Town

As starts to a league season go, being on minus 30 points before you have kicked a ball can't be easy.

And that's how Luton Town found themselves in 2008-09 after being found guilty of a number of financial irregularities.

Mick Harford led the Hatters to the Johnstone's Paint Trophy and they had a solid season.

However, the points deduction was too much to withstand and they were relegated to the National League.

Middlesbrough

Back in 1996, Middlesbrough called off a game against Blackburn Rovers with 24-hour notice.

The Teeside club claimed that 23 players were out sick, injured or suspended which meant they couldn't feel a team for a crunch relegation clash.

The FA hit them where it hurts - in the Premier League. They were deducted three points.

Cruelly, they were relegated - two points from safety with a better goal difference than their rivals.
