We have a good backup in Digne, but I'm happy he isn't out for longer. Maybe if Digne plays well and Alba isn't at top level before the City-game he could get rewarded with some gametime in the CL.
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.
