Napoli president Aurelio De Laurentiis claims he has offered Manchester United one million euros to play his side in a friendly game in a bid to raise the Italian outfits international profile. The proposal - worth £880,000 - is for United to play at the San Paolo stadium in Naples.
The Serie A outfit hope the English champions will accept the invitation.
Speaking on Tuesday, De Laurentiis said: "I have offered Manchester United one million euros to come here and play a friendly against Napoli. I am awaiting a reply.
"My aim is to bring Napoli to be among the top teams, not just in Italy, but at international level.
"There is a lot of work to be done."
