Manchester United will need to hand over £127m if they want to secure Kalidou Koulibaly.
The Senegal international is a long-term target for Ole Gunnar Solskjaer, who wants to add more quality to his ranks in the summer.
And, according to Italian news outlet Corriere dello Sport , Koulibaly has a release clause that can be triggered in June.
His £127m asking price would smash the transfer record for a defender, which was previously set by United when they paid £80m for Harry Maguire from Leicester.
Solskjaer won’t have a free run at securing his signature, though.
PSG have been actively courting Koulibaly and are willing to give him a four-year contract worth around £10m.
It’s understood Napoli might be forced into parting with their prized asset if they fail to secure Europa League football next season.
The Serie A giants have had a challenging campaign and axed Carlo Ancelotti before Christmas.
Gennaro Gattuso is now in charge at the Stadio San Paolo.
Solskjaer, meanwhile, spent big again during the January transfer window.
Bruno Fernandes was finally snapped up from Sporting Lisbon after a protracted transfer saga.
He made his debut in an underwhelming 0-0 draw with Wolves in United’s last Premier League encounter.

The Red Devils are currently enjoying some warm-weather training in Spain.
Solskjaer says the Spanish jaunt will be important for Fernandes.
“He’s had a few days back home to organise,” he added.
“He’s going to have to move house and say his goodbyes back home, so he’s ready.
“He wasn’t 100 per cent happy with his debut and there’s more to come, so that’s a good sign.”
