Sao Paulo - Brazilian club Santos demanded a six-month suspension for superstar striker Neymar on Thursday, claiming he breached transfer conditions when he moved to Barcelona in 2013.
GloboEsporte also reported that Santos are seeking €57 million in compensation from the 23-year-old Brazilian.
"The player should be punished with a suspension of six months from any official match," Santos demanded in their request to FIFA, the website reported.
The player should also "forfeit all benefits, directly or indirectly, received as part of the transfer".
GloboEsporte added that Santos are claiming Neymar "acted in bad faith" and violated the disciplinary code of world governing body FIFA when he moved to Spain.
Brazil captain Neymar has been embroiled in controversy in recent weeks.
In September, a Brazilian court froze €42 million in assets belonging to the player over tax evasion allegations.
On the pitch, he was suspended for this week's World Cup qualifiers against Chile and Venezuela after being given a four-match ban for being sent off at this year's Copa America tournament.
