The French winger has joined the club on a free transfer.
This week saw Hatem Ben Arfa's reported move to Ligue 1 side Nice apparently fall through. FIFA have ruled that Ben Arfa has already played for two teams this season, as he played during a loan spell at Hull City and in an under-21 game for Newcastle United, which was deemed as official by the football organisation. Players are not allowed to play for three teams in one season.
"I am optimistic for Hatem. There is arguments on this issue in our favour and we could not understand Hatem not joining us."
"[If he didn't join] That would mean that there is a real will from some negative people and that I do not want to believe it. "
Ben Arfa joined Nice on a free transfer earlier in the month after cancelling his contract with Newcastle United by mutual consent. The French international struggled on a loan spell at Hull this term and was desperate for a return to French football.
In fact, he told the media at the time of his move, as quoted by The Chronicle, that he would have turned down Real Madrid for Nice - not that Los Merengues were knocking at his door.
Hopefully FIFA see sense, for once, and allow Ben Arfa to get his career back on track in the south of France.
