For this reason, nothing is impossible in football, sometimes we are sure the bet in the club is much stronger but in fact lost quite easily. This is sometimes in the prediction based on the statistics of the strength of the team. Regarding Real Sociedad and PSG PU. Statistically, actually PSG should have things that are much stronger both of them compete quite significantly and tightly. And it's true, whoever the winner is, they deserve for this, because sometimes the match at UCL is quite different in the euphoria. Either Mbappe will stay on PSG after the transfer market or not, this will definitely give a significant effect on PSG itself.
The match is carried out in 90 minutes of normal time so in this case we also have to know that any possibility can definitely happen in this case regardless of how probabolity the bookmakers who definitely have a favorite in the match (in this match is PSG) but still it cannot be used as a belief that PSG will win easily.
This is the Round of 16 where anything is possible so given the current odds, every chance is there.
Indeed, in terms of experience and club strength, PSG is definitely the favorite in this match and that cannot be denied because anyone must know their strengths and advantages compared to Sociedad but on the other hand Sociedad is also not a club that is easily defeated. This is an opportunity for a small club like Sociedad to be able to seek popularity so indeed in this case they certainly don't want to miss the opportunity they have.
