Cant see us buying two CM's unless Eriksen leaves. So I think this one is secondary to Ndombele. I wouldnt waste time following this until the Ndombele saga pans out. Which will take ages as Lyon are obviously waiting for the inevitable PSG move and Levy faffs around counting his pocket change.
Ndombele should be the replacement for Dembele and we need another player to play the Eriksen position even if he stays as he plays far too many games.
