The offer that Inter have reportedly made to Napoli is for €15 million plus Alexis Sanchez. This will almost certainly not work because the €7 million a year wages that Alexis Sanchez earns are far too high for Napoli to pay.
Aurelio De Laurentiis has made it clear that it would take €30 million to sign the Neapolitan this summer, but that is a figure far too high for Inter.
As has been reported by Corriere dello Sport, Insigne is very keen on joining Inter as they have offered him €6 million a year for four seasons. With just one year left on Insigne‘s Napoli contract, Inter could revisit the situation in January or the summer of 2022.
