Roma are in advanced talks to sign Ivory Coast international Gervinho, while Premier League new boys Crystal Palace are thought to be chasing Chamakh.
Wenger is willing to let the pair move on as he looks to free up some funds for his own transfer plans, however the Frenchman insists there has been no movement on the future of another unsettled forward Nicklas Bendtner.
Eintracht Frankfurt have been linked with a move for Bendtner, but a move has fallen through for the Danish international.
Wenger admits he will know more on the possible transfers in the next 48 hours and he confirmed the deals for Gervinho and Chamakh will be permanent moves.
"Gervinho we are at the moment close to an agreement with a club where he should go," Wenger told the club's official website.
"Bendtner we are nowhere. At the moment he is completely here. Chamakh might go somewhere, it will be decided in the next 48 hours. [They are] permanent moves."
