Nice are furious with Barcelona over their attempts to sign Jean Michael Seri.
Seri has emerged as a major target for Barca this week, but Nice are insisting there's been no official contact.
Indeed,Radio Montecarlo says Nice are fuming after learning that Barca have contacted Seri without their permission.
It's also been revealed a buyout clause in Seri's deal - worth €40m - has now expired.
Nice will now demand well above that figure for Seri to be sold in the coming days.
