Newcastle United handed summer transfer boost as prime target becomes 'unsettled'
The 20-year-old, linked with the likes of Manchester United and Liverpool, was subject of a £35million bid from the Magpies in January.
However, Soumare rejected contract talks with United and has reportedly become unsettled at the Ligue 1 outfit.
He hasn’t featured for Lille since the closure of the window, and Galtier was quizzed on his recent omissions.
“There is a situation at the club that I do not comment on," Galtier told French newspaper L’Equipe.
“In seasons, there can be tension between a player and his club. We’ll settle this internally and find a solution."
Galtier added: "Under these conditions, I, therefore, decided to work on two other options this week [Cheikh Niasse and Jean Onana]."
Newcastle could be open to revisiting a deal, however any decision will likely come down to the player.
