The director has indicated that the club intend to strengthen their squad during the winter window, although he stressed that any decisions will depend on their position and the opportunities available when the market opens.
Speaking to Radio Kiss Kiss Napoli, Manna also reflected on the team's recent draw against Lazio at the Stadio Diego Armando Maradona. He was encouraged by the response after half-time and believes the return of injured players can provide a significant boost to Massimiliano Allegri's squad.
The injury situation has been a major issue for Napoli, but Manna refused to use it as an excuse for inconsistent results. He acknowledged that the team have produced good performances without always collecting the points they expected.
The sporting director also addressed the club's January strategy, making clear that discussions are already taking place with Allegri and president Aurelio De Laurentiis.
"We certainly have fairly clear ideas," Manna said. "Then we have to see how we arrive in January and what opportunities will be available at that time. I don't think it is right to name players or indicate positions now, out of respect for the players who have to take us through to January. But we certainly know where we want to intervene."
Manna also reflected on the club's recent transfer business, admitting that Napoli could have made better use of their spending during the previous year. The club are now looking to identify opportunities that can improve the squad without compromising their financial planning.
One of the players discussed was Alessio Cacciamani, the young Torino winger who previously impressed during his time with Juve Stabia. Manna acknowledged Napoli's interest in the 2007-born prospect but was careful not to suggest that a transfer was imminent.
"He is certainly an interesting prospect. He is a player born in 2007 who had an important season last year with Juve Stabia and is showing that he has potential," he said.
"To go from that to saying he is a Napoli player, however, is a big step. There are him and many other players we are following."
Manna was more cautious when asked about Gustavo Varela, the Monza forward who has been attracting attention with his performances and goalscoring numbers.
The sporting director acknowledged the Portuguese player's quality but pointed out that Napoli already have several options in attack, including Lorenzo Lucca and Rasmus Højlund. Giovane can also operate as a central striker, meaning the club are not necessarily looking to add another forward immediately.
"He is a good player, but we have Lucca, who is young and can play in that position. Napoli are covered there at the moment. Then we will see what happens with departures and make our assessments," Manna explained.
He also questioned whether Monza would be willing to sell one of their important players midway through a campaign in which they are fighting to avoid relegation.
"He is certainly a player who is doing well, with important numbers. I don't think Monza will want to give up a player like that in January, given that they are fighting for survival. And if they do, they certainly won't give him away," he said.
Manna's comments suggest that Napoli are considering several areas of the squad but are not yet ready to commit to individual targets. Cacciamani remains a player of interest rather than a confirmed signing, while Varela's situation appears complicated by both Napoli's existing attacking options and Monza's likely reluctance to sell.
The club's immediate priority is to reach January in a stronger position, maintain greater consistency and then take advantage of the opportunities available.
