Barca needed more then Suarez and goalies, their depth has been a joke. When they were signing Suarez and the goalies they arrogantly thought the ban would be overturned, it wasnt and they had to rely completely on their starting 11 to stay healthy. Which it did most of the time weirdly enough except for couple months injury for Messi.
Now they got Alex Vidal and Turan, plus looks like they signing Nolito and Sane from Schalke so they dont need to rely on average Barca B level players like Sandro, Samper, Munir etc.
