PSG remain keen on Chelsea midfielder Willian.
Off contract at the end of this month, Willian is fielding interest from across Europe.
UOL says PSG chief Leonardo is keen on bringing the Brazil international to France this summer.
Should they lose Neymar to Barcelona, Leonardo will move for Willian as a replacement.
And it's claimed if no deal occurs, then Barca will choose the Chelsea midfielder as an affordable alternative.
