Im pretty sure that PSG will buy "star" players if they failed again this year (UCL).
PSG has offered a crazy contract 3 times bigger than Madrid bid to Mbappe, the club financial must be healthy.
This year might be not the year for PSG, but next year will be different.
Every year is always different, because this can be seen through every season played by all teams in any league and for PSG. It seems like they can only hope for trophies in their own local league, while the Champions League trophy is still very difficult because here there are still many obstacles that PSG must overcome. Apart from that, PSG has also had three stars for their attack line in previous seasons, but PSG has also never succeeded in the Champions League.
