For some reason, I also had doubts about PSG this season, they don't seem ready and their strength is only strong in Ligue 1, but not in the UCL league. Even though they are trained by a great coach like Enrique and have star players, they have not been able to show their toughness in the UCL. Just look at PSG qualifying for the round of 16 through luck only with a difference in goal difference with AC Milan.
I think Sociedad will win the match, because Real Sociedad's game is so solid in defense, very good at controlling the ball, and killing counter attacks through player Kubo.
PSG's performance at the start of this season did indeed decline slightly compared to last season, but slowly they can continue to develop their team's performance in a more positive direction and that makes their chances in the last 16 of the UCL even greater and the opponent they face is Real Sociedad, if We look at the quality of both teams. I think PSG is a little better than Real Sociedad, so I don't doubt that PSG's percentage of getting to the next round is much greater than Real Sociedad.
If we compare PSG and Real Sociedad, I think PSG still has a better chance than Real Sociedad of winning and qualifying for the quarter-finals. Even though it is true that Real Sociedad also won group D, leading over Inter and only goal difference is the difference, but that doesn't mean Real Sociedad is better than PSG.
Because after all, playing in the knockout phase of the Champions League clearly has different pressure too, what's more PSG is a team that has good dominance in Ligue 1 . Also, basically Enrique is used to facing or against La Liga teams and with the experience Enrique has like that. So ya, of course Enrique really understands the right strategy for playing against Real Sociedad later and thus, of course PSG has a very good chance of beating Real Sociedad.
