Well according to what's on ground concerning OSG, I think this will be one of the games like that of PSG Vs Brest that finished not too long ago in the play offs. This PSG team will so dominant, out perform and thrash Aston Villa in the Quarter finals. PSG this season is serious with the champions league and I think as in the person of Enrique as their coach will make sure they perform better because they have something at stake, which is having not won the competition before. PSG is just as formidable as Barca this season, both amongst both I don't know which is stronger.
