Representatives of PSG and Neymar arrived at La Liga's offices on Thursday to deposit the £198m to trigger his release clause from Barcelona...
...but the organisation has not accepted it, report AS.
The organisation deems it impossible that PSG can finance a move for the Brazilian without violating the Financial Fair Play regulations imposed by Uefa..

A statement to BBC Sport reads:
"We can confirm that the lawyers of the player (Neymar) have come to La Liga to deposit the clause and that it has been rejected. It is all the information we will give so far."

How are buyout clauses activated?

Confused? Yeh, me too, but this should clear matters up:
The biggest difference between Spanish buyout clauses and release clauses more common in other big leagues around the world is the manner in which they must be triggered.
Rather than the buying club merely paying the selling club the amount set by the contract, the player himself must buy himself out.
This is done by depositing the amount of the buyout clause with La Liga to release the player from his contract. La Liga then pass the money onto the selling club.
Normally this will require the buying club to pay the player the sum of the buyout clause up front.

Standby for more updates as they unfold.
