I think everyone has similar thoughts about PSG. What I will point out will be more interesting. So, if PSG surprises this year and reaches the semi-finals or finals, will this success be Enrique's success? Maybe if such a thing happens, Mbappe will stay in the team and with a few great transfers, PSG will be one of the favorites next year. This probability is very low, but what if it happens? That's when PSG can catch fire again.
It is very easy for PSG to dominate Ligue 1 and dominate other domestic competencies with the top players they buy every time the transfer window opens, but winning the Champions League is not as easy as buying players. In fact, PSG was only able to advance to the last 16 in the last seven seasons, they reached the final in the 2019/2020 season, then in the following season their progress stopped in the semifinals.
This season the PSG squad is under the guidance of Luis Enrique who has experience in the UCL, but their inconsistent performance makes their journey very difficult when facing big teams. I don't think PSG can surprise this season, they qualified for the round of 16 due to luck after fighting hard in the group stage.
This season's UCL trophy is not for PSG, there are still other strong teams who always perform consistently who are better prepared to fight for the trophy. Luis Enrique must develop a strategy with a more solid team strength if he wants to bring PSG to the UCL trophy.
Yes, it's true that they can very easily win trophies in League 1 because the strength of other clubs is not as big as PSG, which has good and quality players, while other clubs in League 1 don't have star players like PSG. However, I see that only Monaco was able to challenge PSG before Monaco sold Kylian Mbappe to their arch rival, so that Mbappe has become the key player that PSG has to date and PSG has returned to being the strongest club and dominates League 1, but yes, winning the Champions League is not as easy as in League 1 because the Champions League is full of clubs that have great strength, such as Real Madrid, Manchester City and Bayern Munich, so PSG will not easily win the title if PSG has not surpassed these three clubs.
Yes, it seems that this season PSG has not had the opportunity to win the Champions League title because there are still consistent clubs such as Real Madrid and Manchester City who got perfect points in the group stage but Bayern Munich had to experience 1 defeat which caused their points to not be perfect like their rivals. This is strong, while PSG is not very consistent and did not even come out as group winners so I am not sure if PSG can win the Champions League trophy this season although it is too early to say now.
