Talk of Neymar's future dominated this summer's transfer window.

The Brazilian was tipped to make a return to Barcelona after two troubling seasons at Paris Saint-Germain. 

After his £200 million move, injury has hampered Neymar's progress and he's been in and out of the team. A number of off-the-field issues have also strained his relationship with the club. 

Both parties have reportedly had enough, with the forward pushing for a move away while PSG were listening to any serious offers they received.

Yet, no deal was reached before deadline day passed. Instead, Neymar will remain in Paris, for one more season at least. 

But don't expect this to be the last we've heard about the saga. According to Mundo Deportivo, the ex-Barca star will be looking to force his move once again in 2020. 

And next summer, he'll have football's governing body on his side. 

The Spanish paper reports that in effect, FIFA will be able to set Neymar's transfer fee in 12 months, as he'll have fulfilled his 'protection period'. 

That regulation has been put in place to help players without buyout clauses and is active after a football plays three full seasons or three years at a club.

After that time, if a player maintains the same contract as when he signed without having renewed, FIFA recognises the right to leave a club, paying compensation.

Per Mundo, 'the amount of this compensation is calculated thanks to a formula that takes into account what the player cost in his day and the amortization of the signing, among other variables'. 

Apparently, Neymar's agents have already consulted FIFA and know that for an amount close to €170 million, they can buy his freedom next summer.

That's very interesting indeed, considering PSG were demanding a lot more than that from Barca this summer.

But in 12 months, that power will be taken away from them and instead it will be FIFA who decide Neymar's fee.
