As i said in the other thread, I think he should have taken Teji Savanier as a sub/alternate starter instead of someone with superflous strengths like Fofana. The guy has been among the best attacking mid in ligue un the last 3 years (definitely the best french one), with a lot of refined playmaking and creative supporting characteristics that the midfielders in the squad don't possess or haven't yet fully developed. Sure, he's too old to be part of the team for long, but as a one-tournament option that had an excellent season he's ideal for some of what France are lacking.
He's a late bloomer though, so will tend to be dismissed/overlooked. I watched more of ligue 1 than any other top five league last season (mainly for Monaco) and his technical/creative level is more decisive right now than someone like Vitinha or Tchouameni, but with his age and not playing for a big team, he's not going to get any hype.
tbf i don't speak much french or follow their football media so maybe he's already voluntary retired from possible national team selection.
