The Evening Chronicle says Stainrod has had his licence suspended by the FA.
Stainrod is a close friend of the French international and worked as a translator for Ben Arfa when he completed his move to Newcastle two years ago.
However, the FA have released the following statement: "On 10 February 2012, an Independent Regulatory Commission found Stainrod to be in breach of FA Rule F2, for failing to provide documents requested by The FA.
"He was ordered to provide the documents within seven days. Stainrod appealed that decision.
"Stainrod then withdrew his appeal with the consent of the Appeal Board on 27 April 2012, however, the Appeal Board ordered that he provide the requested documents by 4pm on 4 May 2012, otherwise his registration with The FA as a Registered Overseas Agent would be suspended with immediate effect.
"No documents have been received so Stainrod's registration is now suspended with immediate effect."
