If Digne plays it is most likely he will face Vazquez, who is not particularly fast. Any defender will get beaten if he is left in a 1 on 1 situation vs a skillful dribbler. Neymar or the LCM provided zero cover for Digne when he was playing. Roberto's ass was saved by Rakitic or Masche (when Umtiti was playing) at least.
He's bad one on one, whether Neymar is there or not
