Ligue 2 side Valenciennes are keen to add another attacker to their ranks after signing South African forward Lebo Mothiba, and are monitoring Simon Diedhiou and Jerson Cabral.
Faruk Hadzibegic's side began their campaign with a 1-1 home draw against Gazelec Ajaccio on Friday evening, and the Bosnian coach is keen for more firepower before the window closes.
He's already added Mothiba on loan from LOSC Lille, although the South Africa U-23 international is unproven in the second tier.
According to French source La Voix du Nord, Hadzigebic has set his sights on Diedhiou and Cabral after identifying them as potential solutions.
26-year-old Senegalese frontman Diedhiou has returned to KAA Gent after a loan spell at Mouscron, but does not appear to be in coach Hein Vanhaezebrouck's plans.
Cape Verdean Cabral - who played for the Netherlands at youth level - returns to relegated Bastia after a spell on loan at Sparta Rotterdam, but is unlikely to be retained following the Corsican club's drop to the third tier.
Another striking option for VAFC is Franco-Moroccan frontman Medhy Guezoui, who scored the equaliser in Friday's draw.
