Napoli president Aurelio De Laurentiis has revealed that the Italian club have £42m to spend on new signings in January.
The Italian outfit currently sit third in Serie A following a positive start to the season, but De Laurentiis has promised boss Rafael Benitez more funds in the winter window.
"In January, I will have to spend another €50m (£42m) on players if we are to keep competing," he told Il Mattino.
"It is not easy to bring success if you don't spend enough money, and that is something I have to accept.
"It is crucial that we remain in the Champions League past Christmas in order to attract the top players, and Benitez knows that."
A number of new signings arrived at Napoli in the summer.
