If they failed to win it when they had Messi, Neymar and Mbappé, then I don't think they can do it this season. I even have doubts if they can reach the Semi Finals. Mbappé alone is not going to help them. I saw how thy played in the Group stages and although their group was labelled as group of death, 2 draw and 2 losses far low for a team looking to challenge all the way to the finals
Agree with you. PSG best era was when they had trio strikers Messi-Neymar-Mbappe. If in that era they couldn't win the trophy, it is more impossible to win it in the current era. We don't forget that they are very difficult to qualify to knock-out round this season. They were almost eliminated in group stage by AC Milan because they have the same total points. How they can win UCL trophy if they were difficult to qualify to the current round? Sure, it seems hard to achieve the semi-final round. Let's hope PSG can win against Real Sociedad first before predicting PSG to be the champion. It Real Sociedad defeats them, there is no way to win UCL trophy for PSG.
No matter how ideal it is when Messi and Neymar are still there, it is still not a guarantee if you are in the UCL. Because it wasn't enough to be filled with mega star players, especially when stability was only in the attack line, while PSG midfield at that time was not very promising. UCL is not about mega star players anymore, but to be able to survive you need to have a strong mentality in motivating yourself and the ingenuity of a coach when setting strategies.
PSG must realize that Real Sociedad is not an easy team to beat. They are representatives of Spain whose existence needs to be watched out for at UCL. Even though they are not the top team, the mentality of Real Sociedad players will make PSG's game difficult. I think PSG and Real Sociedad have the same chance of winning this match, but with a narrow score.
