The France international midfielder, who scored 14 goals for Montpellier in Ligue 1 last season, is set to join Siem de Jong, Ayoze Perez and Jack Colback in moving to Tyneside
Remy Cabella has arrived for a medical ahead of his move to Newcastle, Goal understands.
As revealed earlier on Sunday, the midfielder is one of three deals which the Magpies are very close to sealing.
The 24-year-old, who scored 14 goals and made five assists in Ligue 1 for Montpellier last season and was part of the France World Cup squad which made it to the quarter-finals, has been a long-term target for Alan Pardew's side.
Newcastle hope to follow the acquisition of the attacking midfielder with Netherlands international Daryl Janmaat and Monaco striker Emmanuel Riviere before they depart for a pre-season tour of New Zealand late next week.
Pardew has moved quickly to bolster his squad this summer, with Siem de Jong, Ayoze Perez and Jack Colback all having already arrived at St James's Park.
