Neymar, Barcelona and Santos will stand trial on fraud and corruption charges over the transfer of the Brazilian forward after their appeals were turned down by Spain's High Court on Monday.

Neymar's mother Nadine Goncalves and the family company N&N also had appeals rejected.

"Santos FC, Barcelona FC, Neymar, his mother Nadine Goncalves and N&N, the family company, have lost their appeals to have charges of fraud and corruption dropped," the High Court said in a statement.

The case stems from a complaint by Brazilian investment group DIS, which owned part of Neymar's transfer rights.
