As the January transfer window looms, so does silly season.

According to multiple reports, Kylian Mbappé is unhappy at Paris Saint-Germain and is actively seeking a move away from the club.

Even though the 23-year-old inked a contract extension with the Paris giants in May, that doesn't deter him from looking elsewhere.

Despite playing alongside Neymar Jr. and Lionel Messi, the France international feels "betrayed" by the club and has had "enough," per Julien Laurens of ESPN.

Here is the tricky part: Which teams in world football can afford Mbappé?

A move would have to make sense from a sporting perspective as well.

The list may be short, but there are a couple of options. Here are four potential landing spots for Mbappé.

Real Madrid

The intelligent guess in this situation is for Mbappé to circle back to Real Madrid.

After their very public transfer saga, the Spanish giants are logically the favorites to acquire the Frenchman.

However, will Real Madrid want to go back to him after his public rejection in May?

Looking at Madrid's future, Vini Jr. and Rodrygo are the core.

Adding Mbappé would improve the squad. But with such highly rated talents as the two Brazilians mentioned above, why would they ruin the foundation they're building for a player that rejected them months earlier?

Mbappé may want to leave Paris, but if reports out of Spain are any indication, a sale is unlikely to happen.
