Running a financially sound football club must be a difficult job; despite the millions earned each year through television rights, the pressure on shelling out astronomical fees on new signings and keeping the current crop happy with substantial wage packages can be over-bearing, especially when results don't go your way.
A new research initiative by Europe's governing football body, UEFA, has revealed which clubs possess the highest amounts of debt, despite the introduction of the financial fair play regulations.
As reported by the Independent, here are the 10 European football clubs with the most debt as per the European Club Football Landscape report...
Italian teams will feature prominently in this list and the first is Roma, who have a debt of €208m. Nonetheless, this has not stopped the men from Italy's capital exerting themselves as one of the biggest and most consistent teams in the Serie A.
Despite returning to their rightful place at the summit of the Italian top flight, following relegation amidst the Calciopoli scandal, I Bianconeri continue to have some financial issues, although much of this is resultant of their move to a new stadium.
Arguably the biggest side in Turkey, Galatasaray top the charts in their homeland when it comes to debt too. The Super Lig heavyweights continue to spend big on transfer fees and wages despite the huge deficit.
7. CSKA Moscow
CSKA Moscow have been Russian Premier League champions three times in the last five seasons, finishing in second place in the other two, so clearly the substantial debt that the Champions League regulars have does not affect their performances on the pitch.
6. AC Milan
One of the most successful European sides of all time, I Rossoneri have fallen by the wayside in recent years, but are looking to get back on top after being bought by a Chinese consortium. They'll be hoping to reduce that too.
5. Queens Park Rangers
The Hoops' time in the top flight will be remembered for a period of big spending, which ultimately could not prevent them from returning to the Championship after just two years in the Premier League. They are the only second-tier club in this list.
Valencia's monetary struggles have forced the historically successful La Liga side into a midtable club desperately flogging its stars to keep afloat, which explains the big-money exits of Shkodran Mustafi, Nicolas Otamendi and Andre Gomes in recent years.
3. Inter Milan
Just like neighbours AC, with whom they share the grandiose San Siro, Inter Milan are also useless when it comes to balancing the books. However, new owners mean they will be spending a lot more than they sell, as they aim to get back to their glory days.
The current champions of the Primeira Liga, the Portuguese top flight, Benfica are not so responsible when it comes to managing their finances, with the Eagles clocking up the second biggest debt on the continent.
1. Manchester United
In first position, and by some margin, Manchester United's debt has been protested by fans regularly since Glazer takeover back in 2005. However, the Red Devils' unprecedented annual revenue means that the Premier League club are one of the most valuable teams in the world.
