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.
Actually, the main issue being debated is not about the title in UCL or league 1, but the fans only expect PSG to continue to strengthen consistency and focus on several competitions and maximize performance in those competitions.
So when PSG is able to maintain stable performance to focus on certain competitions, I am sure PSG is able to pursue the desired title. For example, PSG has started to appear consistently maintaining every strategy to maintain the final result with a draw or win in the UCL competition and will appear normally in league 1. I am sure that is a little unreasonable but it is one of the best ways for me.
We will see in the future when PSG is able to appear impressively in the UCL until the final round, of course in other competitions PSG will also appear normally but have a draw or refuse to lose.
