The main goal PSG has is the Champions League title and now that they are in the round of 16, there is nothing more they can ask for as of now. Their focus is on those games and there are rumors all the time about Mbappe. Now there are new rumors talking about PSG going for a last resort offer for Mbappe to extend his contract, but as long as no officials confirm this, I doubt anything can be relied upon.
UCL has always become the main target by PSG since a few years ago but this club has failed many times on getting it. No doubt that if people are starting to feel doubt about the progress of PSG this season. The result will remain the same as previous seasons if PSG will fail in UCL this time.
It's impossible for PSG to extend his contract caused by mbappe still stands with his previous choice to leave from PSG after his contract will be running out. It's only matter of time till we will see him join in the other club.
It's very funny to see PSG who are very ambitious about wanting to win the UCL title for the last few years but they continue to fail every year. Everything has been done, including installing a deadly trio on the front line containing classy players such as Messi, Neymar and Mbappe, but their presence cannot bring PSG to the main podium to celebrate their success.
Mbappe has seen his condition at PSG realistically, he only earns money there but has very little chance of winning the UCL trophy. Moving from PSG was the final solution for him who still really wanted to experience the pleasure of touching this prestigious trophy. He is still young, his career still has a long way to go, moving to another club would not only open up the opportunity to win the UCL trophy but could also give him the chance to win the Ballon D'or.
