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.
PSG confidence has increased after beating Liverpool and their motivation to continue is very high but on the other hand we also cannot deny that Aston Villa also has the same determination. They are a team that was not predicted from the start to qualify this far in the Champions League. In terms of strength, of course PSG is superior but Aston Villa must also be preparing a surprise that we cannot predict.
