FIFA said Tursday it was investigating Brazilian superstar Neymar s complaint over an unpaid loyalty bonus from Barcelona in the increasingly bitter feud with his former club since his move to Paris Saint-Germain.
A FIFA spokesman said the complaint was "pending and being investigated" and he could not comment any further.
Barcelona are refusing to pay a 26-million-euro ($30.6 million) bonus to Neymar for signing a five-year contract renewal last year.
In a separate issue, the Catalan giants are seeking 8.5 million euros in compensation from Neymar for breach of contract following his world record 222-million-euro move to PSG in August.
Neymar s family hit back on Tuesday with their representatives expressing their "surprise" at Barcelona s compensation claim "given that the player fully respected the contract valid at the time".
