But what you've done is set an almost impossible criteria. Very few players get to the “star” development stage in ligue1 because of the economics, it's only the 6th richest league in Europe behind the PL, Bundesliga, La Liga, Serie A and the Championship. it’s a bit like saying “but who was a star in league 2 and then a star in the PL". There is currently only one team in Ligue1 who can buy and retain established "stars". Even Monaco can't do it any more.
If you ignore your impossible criteria, then loads of players have come out of the French league and been stars in the PL (and the other major leagues). There isn't a country that has exported more/better quality footballers in world football. Look at all the top clubs over the last ten years in the England, Italy, Germany, Spain they are rife with e-ligue1 stars from Drogba, Kante, Hazard, Gallas, Essien, Evra, Ribery, Lizerazu, Abidal, Diarra, Varane, Benzema, Umtiti, Tolisso, Aubamayang, Henry, Pires, Abidal, Griezman, O Dembele, Lloris, Pogba, Kante, Coman, Pjanic......it just goes on and on - and most (bar a couple) of those are French players I can think of, not the other nationalities (African etc)
And Pogba is a fantastic footballer, even last year, playing in Mourinho's ultra pragmatic Cm2 system (which isn't ever going to be right for him) only 2 other CM's were more productive in terms of goals/assists than his 10 assists and 6 goals (Silva and KDB) and they both played in CM3's or occasionally as AM's all season.
