Santos have asked FIFA to hand Neymar a six-month suspension for what they are calling non-compliance of contract terms during his transfer to Barcelona, according to Brazilian daily O Globo.
The club are seeking the six-month ban and €55 million in damages, alleging that Neymar did not keep the conditions of a transfer, an unnamed source has told the Brazil daily.
Neymar moved from Santos to Barcelona in 2013.
