PSG having lethal attack which can break their defence and backbone as well and with this all Real Sociedad is having no attack which can give them good results in last three games they have two games without scoring any goal which is also giving all details how things are working for them in this season in La Liga in group stages they were not able to score goals against Inter Milan and Salzburg in away game and at home as well.
If you compare PSG with Real Sociedad then I can say that PSG is much better than Real Sociedad. Many people say Real Sociedad is much better because they play in La Liga but I see that Sociedad this season has some problems with their defense. This is of course a big weakness because we know PSG has a striker like Mbappe who of course can pose the biggest threat to Sociedad.
