5 reasons why Neymar's €222m transfer from Barcelona to PSG could really happen

5) Spanish tax issues could force exit

The Spanish tax fraud case took its toll on Neymar's familyNeymar is not the only La Liga player to have been embroiled in a tax scandal in Spain but his case has been one of the most high-profile ones in the country. In the Brazilian's case, it has to do with unpaid taxes over his transfer from Santos to Barcelona.

Although he was officially signed for €57.1m, his actual fee is closer to €86.2m when investigations revealed that two companies owned by his parents received millions in payments that required them to pay €9.1m in taxes.

Prosecutors wanted a two-year jail term for Neymar and numerous appeals from the club and the player's side were rejected. While first offenders in non-violent crimes do not have to rot in a Spanish jail if the sentence is two years or less, he will be liable to pay a hefty fine instead.

Neymar may or may not have been complicit in the entire ordeal (it's hard to see how a 21-year-old could have orchestrated such complicated deals). Nevertheless, it is a saga that deeply hurt Neymar and his father (who is probably more culpable in this case).

"I do not want to talk about persecution but if we don’t have a comfortable situation to work we can not stay in Spain," he had said last year when a contract renewal was mooted.

"We never had such big fiscal problems in Brazil. After arriving in Spain, the attacks began and the attacks have now spread to Brazil."

This could be the straw that ultimately breaks the camel's back leading to Neymar putting pen to paper at Paris Saint-Germain.
