PSG have a great mentality and toughness in dominating the domestic league so far, but this mentality and toughness they do not have when playing in Europe, especially the UCL so far, even when they have many star players in the squad, their best achievement in the UCL is only until the final without being able to win the championship trophy, They actually have a strong squad with great players but the easy competition in the league has actually shaped their poor mentality in the UCL, in my opinion, before PSG is able to improve their mentality to be better and stronger, then we will never see PSG win the UCL and this season is likely to be their worst journey in the UCL.
It's high time we stopped deliberating about PSG's dead luck in the Champions league because they can achieve it in a season when no one will expect them to win the trophy. Despite their little efforts in Champions league games, the most important thing is that PSG still dominates the France ligue 1 and they are likely to win it back-to-back again, so had it been that they are not doing well both in the Champions league and the Ligue 1, that is where it could have become a problem. They can't continue thinking about the Champions league so they should just try their best, if they go further, it's fine and if they don't, they return home and take full charge of the league games. They should not fall into a discomfort just because they want to win the champions league.
