The 25-year-old is contracted to French club Toulouse until 2011, but is said to be looking for a new challenge after a disappointing league campaign which saw his side finish 17th a year after qualifying for the Champions League.
It is understood the Magpies have opened initial talks with the player as they consider a possible move and his advisor Sebastien Thiery said: "Achille is ready to play in the Premier League and Newcastle is a team he would relish playing for."
