Not if Vidal plays mate. I've haven't seen such a disjointed Barca team for years.
Busquets is slowing down, Rakitic is not a Barcelona player and the signings of Prince and Vidal are a joke.
Roll on next year for them with the arrival of De Jong and possibly De Ligt.
If they didn't have Messi since Xavi and Iniesta split they'd be seriously struggling.
