The 20-year-old is currently on loan at Atletico Madrid, but it is believed Valencia would prefer selling him at the end of the season.
The Spanish giants are struggling with their financial situation and it is believed they could sell Banega for around £10million.
“We are speaking about a deal for June with my agent,” Banega told Napoli Press. “I know Lavezzi and it would be wonderful to play together in the old team of the great Diego Maradona.”
