Official: Napoli sign Alisson Santos from Sporting CP | OneFootball

Napoli have officially signed Alisson Santos from Sporting CP, on loan for a reported fee of €3m with option to buy for a further €16m.

The left-sided attacking winger is Brazilian, but also has Tunisian citizenship.

There are still some doubts over the precise figures, but Sky Sport Italia claim this evening that the total cost would reach €19m rather than €23m, although there might be further add-ons.

He came to Europe for Leiria in 2024 and EC Vitoria sold him to Sporting CP in July 2025 at a cost of €2.1m.

His profile soared over the last six months thanks to three goals and three assists in 31 competitive games for Sporting CP.

Curiously, all his goals were scored in the Champions League.

Meanwhile, Napoli have also completed the loan of Giuseppe Ambrosino to Modena until the end of the season.
