and this could happen to PSG because I don't doubt PSG's finances which might be able to make an offer to Haaland worth 100 million dollars will definitely make the player think deeper and possibly accept the offer from PSG.
Regarding Mbappe's departure, I am ready to see him go because he has provided many good achievements for PSG and it is time for Mbappe to look for another challenge with a bigger club to get the title he wants.
But if it was PSG I think Haaland would think about signing with them. You have mentioned yourself that Mbappe chose to leave PSG because he wanted to look for another challenge. Actually I don't think there is a difficult challenge at PSG for players like Mbappe or Haaland. If Haaland plays for PSG then he will do what Mbappe did where Haaland will win several Ligue 1 trophies and it will be difficult to compete in the Champions League.
Mbappe wants to leave PSG We are saying this because Mbappe has not yet renewed his contract with PSG. But I wouldn't be at all surprised if Mbappe doesn't end up leaving PSG. PSG management offers Mbappe a lot of benefits as well as high wages. Also this season PSG got an experienced coach like Luis Enrique. So it's no surprise that Mbappe extended his contract with PSG again at the last minute.
If Mbappe leaves PSG, then PSG will definitely need an experienced striker. They may try to bring Haaland from Manchester City. However, it is unlikely that Haaland will leave the Premier League and come to Ligue 1. PSG may try to add Vlahovic or Osimhen to the squad.
People always be speculate about Mbappe future since last summer this because he has made a drama with PSG and at that time Mbappe was refuse to extended his contract although PSG offering to give him contract extension with high salary but Mbappe has decide to leave this team at the end of this season and after his decision now he was linked to several big clubs but the news about Mbappe is still uncertain because after Real Madrid who showing their interest to him reported Liverpool too was taking a part with attempts to gets him
If Mbappe leave PSG then they have to immediately to look for his replacement and indeed PSG has money so buying expensive player isn't big problem for them but it's not easy to buy new players who have equal quality to Mbappe however actually PSG was buy Gonçalo Ramos last summer and this player was purposed to being an Mbappe replacement but unfortunately Ramos still unable to reach his shape just like he was playing at Benfica and 3 goals from 13 matches is really not impressive record from him
Mbappe's future is still uncertain. It is certain that PSG management want to keep Mbappe in France. However, nothing can be said for sure about whether Mbappe will stay in his country or go to England or Spain. Mbappe has been rumored to join Madrid's squad for the past few seasons. But Mbappe eventually signed a contract extension at the last minute each season.
If Mbappe leaves PSG, PSG will definitely need an experienced striker. But even if Mbappe doesn't leave the squad, Luis Enrique is likely to look for a talented striker for his squad. Because he is not interested in tailoring his match strategy depending on Mbappe alone. PSG needs another talented striker. In previous comments, I said Vlahovic or Osimhen would be good options for PSG. Haaland is unlikely to be interested in leaving the Premier League.
