As things stand, the 25-year-old will leave the French champions for nothing at the end of the campaign, having entered the final six months of his current deal at the Parc des Princes.
Mbappe's terms include a 12-month extension option until the summer of 2025, but he made headlines across Europe when it was announced that he decided against triggering the clause.
Determined not to let the world's second-most expensive player depart for free, PSG actively tried to push Mbappe out of the door during the summer market, but the window slammed shut with the France international still at the club.
Over the summer, it was alleged that PSG had threatened to bench Mbappe for the whole season if he did not have a change of heart over his contract stance, and he was briefly made to train with other transfer-listed players.
Such a striking scenario did not materialise, but Mbappe's contract situation remains unchanged, and speculation over the attacker's future is beginning to heat up once again after he admitted that the time will come for him to leave PSG one day.
Real Madrid remain the outright favourites to prise Mbappe away from Paris, although the attacker's entourage have denied reports claiming that their client has already reached a pre-contract agreement with Los Blancos.
In a last-ditch bid to stave off interest from Real again, Diario AS claims that PSG have presented him with a mammoth €100m (£85.7m) per year renewal offer, over three times greater than Real's €30m (£25.7m) salary proposal.
While Mbappe would almost certainly become Real's highest-paid player if he were to finally complete a long-awaited Bernabeu transfer, the report adds that the Spanish giants do not want to create too big a gap between his pay packet and that of his teammates.
Mbappe may have to relent on his salary demands in order to pull on the Blancos jersey, as a separate report has claimed that the 25-year-old is after a weekly wage of £1.25m from any potential suitors.
As well as Real Madrid, Liverpool have supposedly never broken contact with Mbappe's entourage since initially trying to sign him as a schoolboy, but the Reds would not smash their wage structure to welcome him to Anfield.
Teams in Saudi Arabia would easily be able to satisfy Mbappe's economic demands, and Al-Hilal reportedly had a €300m (£257m) bid accepted by PSG over the summer, but the ex-Monaco man rejected the chance to move to the Middle East.
Mbappe has continued to block out the perpetual off-field distractions to score 26 goals in just 25 matches for PSG in the 2023-24 campaign, including 19 strikes from 17 Ligue 1 contests.
The France international dethroned Edinson Cavani as PSG's all-time top scorer last season and now has a total of 238 strikes from 285 games for the capital club, in addition to 102 assists.
PSG sit five points clear of Nice at the top of the Ligue 1 table and are next in action on Saturday, when they visit US Orleans in the last 32 of the Coupe de France.
