PSG's meeting with Sociedad cannot be taken lightly because Sociedad is also not an easy club to beat so that they can enter the round of 16, it is not easy to qualify. That's why PSG must be able to play optimally in the first leg meeting because of course it will be difficult to correct mistakes. If that is done at their first meeting, Luis Enrique must really be able to provide the right strategy to fight this Spanish club.
Sociedad have gone through the group phase well enough so that they managed to qualify for the round of 16 and I don't think they will waste this opportunity. PSG is not an easy opponent but Sociedad also cannot be underestimated because in the group phase they managed to hold the Champions League runners-up to a draw last season in the home and away matches, so they managed to emerge as group winners.
Luis Enrique has to prepare everything because facing teams that are not taken into account will be much more difficult because they don't have too much weight when playing. So there will be unexpected surprises such as several clubs in the group phase beating teams that are much stronger.
Real Sociedad, who will compete against PSG, will be a very difficult match for both teams because both of them are in very good condition. but actually there are differences between these two teams if we look in depth, like Real Sociedad has a fairly strong defense and can always withstand attacks even though they have to play against a strong team but in the attack line they are not too strong, it's just that Real Sociedad attack line players are very smart to looking for empty space to score.
and on the one hand PSG has a very strong attack line with Mbappe but a slightly weak defense can always concede.
I just want to make a little prediction that in the 1st leg PSG will win by a narrow score and Real Sociedad will win in the 2nd leg. the reason I say this is because away or home matches are very influential and these two teams will be very strong at their respective home grounds but to speculate who will qualify, it looks like PSG will qualify but there is no guarantee because as I said before, PSG defense is a little weak and often concedes goals.
