I don’t think PSG is a weak club compared to Liverpool. Football is unpredictable and while Liverpool may be considered favourite in the match against PSG, I wouldn’t underestimate PSG, they are champions in their domestic league and are capable of competing against other top teams in Europe.
PSG History at UCL
In 2023/2024 they reached the semifinals and lost to Dortmund. Not underestimating PSG, but against Liverpool I doubt they can win. Maybe there is not a big chance that PSG can qualify for the next phase, I prefer Liverpool. But PSG's development is indeed quite good, even though their best achievement is only the semifinals. They are always beaten by big clubs from the EPL, La Liga, and finally the 23/24 season from the Bundesliga. This year in the last 16 they also competed with a perfect points team during the new UCL format. So I squeeze PSG has a strong opponent.
