No, at a club like Barcelona no one scouts the opponents. We just appear on the pitch and see how it goes.
As ridiculous as it sounds under normal circumstances. I actually think last season during Tito's relapse, between say Feb and April when Roura was in charge, It wouldn't have been far off to say we probably spent little time on tactics and studying the opponents, at least not what you'd expect under someone like Tata or Pep or when Tito was healthy. It really showed in those ties against Milan/PSG/Bayern, don't you think?
