However, the movie mogul insists the starting price will kickoff at €100 million.
Cavani has been linked with United as a replacement for Dimitar Berbatov and De Laurentiis says: "For anything less than €100 million we will not start.
"Anything below that would upset him, he is not worth so little. He has also renewed his contract, I gave him a good one and he deserves it.
"He's worth more than the English press are writing."
