Sow was integral in Lille's Ligue 1 triumph last season, topping the goalscoring charts with 25 goals after joining Les Dogues on a free transfer over the summer.
His stellar performances have attracted the interest of several top European sides such as Inter Milan, Arsenal and Sevilla.
Sow refused to give a definite answer on whether he will move in January, saying in a press conference: "Only God knows what will happen in the future.
"Right now I represent Lille and I want to remain focused on my club, but anything could happen before the end of the season."
The Senegal international is reportedly valued at €18million and has a contract with Lille until 2013. However, talks to renew his contracts have recently stalled.
