Messi has been staying at the Royal Monceau with his family since moving to France.
But his wife, Antonella, is on the hunt for a permanent residence and appears to have narrowed down her perfect home.
She's apparently eyeing a castle that is listed at a whopping £41 million (₦23.3 billion) on Sotheby's.
The luxurious property, built in 1899, boasts an enormous 30 rooms not to mention an indoor swimming pool, home cinema and gym.
And a personal squash court.
If that wasn't enough, there's also garages and staff quarters on site.
Reports claim Antonella has viewed the castle, but will look at it again with the six-time Ballon d'Or winner before making a final decision.
The player could be swayed by the fact that it's just 15 minutes away from the club's training ground.
Former France President Charles De Gaulle also stayed at the property for three days in 1940 during World War II.
Messi, meanwhile, is in line to make his home PSG debut on Sunday when his side face Lyon.
