We are not going to say that PSG was unlucky because they didn't reach the finals and lost it. From my own understanding, I feel that we are the ones giving PSG too much hype because they don't have a rival in their domestic league. We think that they are very strong, but they come to UCL and mess things up for themselves. PSG need more improvement in order for them to have the chance to win UCL.
A simple but very true understanding. That is why PSG always has difficulty competing with big teams from other leagues when they are in the UCL. Because PSG when they are in league 1 do not have strong opponents that make PSG accustomed to fighting tougher teams. Although every season they can always be present in the UCL, the experience that PSG gets is very lacking to get a title in the prestigious competition. Unless PSG is really lucky when they get a coach who can really bring PSG to win the title in the UCL and slightly ignore the title in league 1.
A good a d tough rivalry at the domestic levels no doubt does helps the team build some level of resilience especially when they go out there away from their domestic league but for PSG, I see beyond that because teams from the Italian league that isn't as competitive as the Spanish and English premier League still does well in the champions League but with PSG they appear to me like they have at some point lacked the mentality to get them the champions League level of competition and so they at this stage still struggle around it even when they have a relatively good team with a fair depth and form.
