While Paris Saint-Germain plans to pursue Lionel Messi in January, they are prioritizing extensions for Neymar and Kylian Mbappe. 

Neymar currently earns €36 million per year, while Mbappe's contract pays €20 million.

Messi's contract with Barcelona pays €60 million per year, which would complicate the contract situations of Neymar and Mbappe should he agree to join PSG.

Neymar and Mbappe each joined PSG in 2017.
