Real Sociedad progress in the Champions League this season cannot be underestimated, they won group D which contained Inter Milan who were finalists in the UCL last season, PSG qualified for the knockout stages by finishing second in Group F. Luis Enrique who serves as PSG coach, is no stranger to Real Sociedad, he previously faced Real Sociedad when he was still coach of Barcelona. Sociedad also has several players who have played for the Spanish national team in the Luis Enrique era.
This is a difficult match for PSG because the improvement process carried out by Luis Enrique in the PSG squad is not completely perfect, they are still having difficulty bringing out their best abilities in the UCL even though they managed to top the Ligue 1 standings. Luis Enrique experience against teams from Spain is very important for PSG, especially now that they are in the knock-out round, a small mistake in the first leg can have a big impact in the second leg.
Yes that's right. PSG should not underestimate Real Sociedad, even though PSG is materially superior, that doesn't mean Real Sociedad won't give a surprise in this match. Apart from that, Real Sociedad is one of the best home teams in La Liga but their biggest strength is their performance away from home.
They are not afraid of anyone and are good enough to play their style anywhere. Based on two matches in La Liga this season they managed to beat Real Madrid and Barcelona, the score was 1-2, and beating Real Madrid 2-0 at the Bernabeu was not an easy thing. So considering Real Sociedad an easy opponent is a big mistake for PSG, I think PSG must be careful with Real Sociedad's game.
