The 27 year old is likely to play in the reserve fixture against Swindon on Wednesday in a bid to earn a move to the Liberty Stadium.
Moussilou scored once in four caps for France U-21’s but opted to represent Congo at senior level – netting on his debut in a 1-1 draw against Morocco earlier this year.
He has enjoyed impressive spells with Lille, netting 24 times in 98 appearances, and Al Arabi, scoring 16 in 20 games.
Moussilou could sign at any time as he is a free agent after departing French outfit OGC Nice 10 days ago.
