Paris Saint-Germain are pursuing a potential signing of Lionel Messi.

Messi can begin negotiating a contract with another team in January.

"I cannot talk about it at the moment," PSG's president Nasser Al-Khelaifi said on Thursday when asked about Messi's future.

Messi has remained close with Neymar over the past few years.

Messi's wage bill will be one of the stumbling blocks for PSG, as he earns €60 million a year at Barcelona, much more than Neymar's €36 million a year or Kylian Mbappe's €20 million a year.
