Paris Saint-Germain have perhaps escaped UEFA sanctions over their 222-million-euro acquisition of Brazilian superstar Neymar, but they may run into trouble with Financial Fair Play (FFP) down the road a report from Forbes concludes.

The deal which, including Neymar's annual net salary of 30 million euros and other bonuses, goes over 550 million euros will have to be reduced to at least a loss of under 60 million euros in three year's time or the French club will face repercussions.

Such was PSG chairman Nasser Al-Khelaifi's confidence in the profitability of the deal, he claimed it had increased the value of PSG to 1.75 billion dollars overnight, meaning that its value increased by 909 million dollars from where Forbes had valued it in June.

Many have already pointed to the array of new opportunities the Neymar signing will present. The Brazilian, the third most marketable footballer in the world behind Cristiano Ronaldo and Neymar, will bring about more jersey sales, new and better sponsors and boost PSG's share of the broadcast rights which they currently enjoy.

Playing in the Ligue 1, the poorest of Europe's top five leagues, means that their earnings from TV revenue will always be constrained to a certain threshold. PSG receive 19 per cent of the broadcast revenue generated by the French league, with the total amounting to a 722 million dollars. Their domestic TV revenue is not going to change any time soon as the league have a deal in place till 2020. They can only bolster their earnings in this department by progressing in the Champions League.

There may also be an increase in sponsorships, but that would be more profitable for Neymar than the club. If the Brazilian is the superstar that Le Parisiens hope for, then sponsors would be more likely to flock to him, rather than his club.

PSG also have some dubious sponsorship deals in place already, which may deter others from linking up with the club. In 2014 UEFA found that PSG's deal with Qatar Tourism Authority (QTA) exceeded fair market value, which led to a fine for falling foul of FFP. In 2016, the Paris club signed a renewed deal with QTA for 175 million euros a year.

The jersey sales are another big talking point. 10,000 jerseys at 150 a pop and PSG are 15 million euros richer. Except they aren't. Almost all deals with jersey makers are based on royalties of up to 20 per cent, which means PSG would earn 1.5 million euros. The deal may be renegotiated, but even then it would be nowhere close to the numbers being tossed around.

But what about spectators? Surely signing Neymar will get them flocking to the Parc des Princes. In reality PSG have been selling out their games despite ticket prices being higher than at any other venue, so that too will not increase unless the stadium is expanded and its capacity raised from the current 48,000.

The place that PSG earns most of their money is from the 'other income' column. An afterthought for most teams to bunch small sums together, for PSG it is their gold mine.

The average Ligue 1 team has 'other income' of seven million dollars. PSG have 265 million. What makes up this infamous amount of money is the deal with the QTA.

Yet for all their revenue PSG are also the biggest spenders in the French league. They pay 28 per cent of Ligue 1's wages, with their payroll at a staggering 350 million dollars per year.

When you add it all up, there are precious few reasons to think that PSG stay on the right side of FFP much longer, let along can financially profit from signing Neymar.
