Sochaux have confirmed that Newcastle have moved for Modibo Maiga while they are in 'advanced' talks for Leeds United's Max Gradel.
The Magpies have been tracking the Mali international throughout the summer and are believed to have offered €8million (£7m) to secure his signature.
Sochaux chairman Alexander Lacombe is against losing one of the club's brightest talents as he looks keep the team as competitive as possible.
However, he has hinted the 23-year-old could depart should a replacement be found and the club are hopeful of landing talented winger Gradel.
Gradel is an Ivory Coast international and Leeds are ready to accept a transfer fee now rather than lose his services for free next summer when his deal expires.
The former Leicester City man has excelled since moving to Elland Road and is believed to be open to joining Sochaux in order to further his career.
"There has been an offer from them (Newcastle)," confirmed Lacombe. "But my goal is to maintain a competitive team.
"I won't sell Modibo without having found a replacement.
"We hope to finalise the deal," Lacombe added on Gradel. "It's a deal which is at an advanced stage."
