You can't compare this PSG team with the Barcelona team that Luis Enrique once managed and won the Champions League title with. PSG has several good names on paper, but they have had their problems in the Champions League as well. They could not beat Dortmund in the second game and they got destroyed by Newcastle 4-1 in the first game and couldn't win the second game either. Where is Newcastle now? Out, they are not even in the Europa League.
I think these results in the group stage are reason enough for Real Sociedad to assume that they have a good chance to progress to the quarterfinals. I am not saying they are the favorite, but I am saying they have a good chance.
It's true that PSG is compared to Barcelona when luiz enrique coached is not comparable, in the era enrique coached the Barcelona squad was the champion squad of the guardiola era. there are big names messi xavi hernandez and more. so if luiz enrique's size is clearly not comparable. but for real socieded to beat PSG is also not very easy, which is favored in this match is clearly PSG. in addition to his squad with many stars enrique is also very familiar with how to play Spanish clubs. besides being Spanish almost his entire career enrique also played in the Spanish league.
And Real Socieded can be the group winner is also very lucky not because of the good quality of the game.
