Khvicha Kvaratskhelia could be valued by Napoli at €100m (£86m) next summer due to his strong form this season, according to the attacker's agent Christian Emile.
There is currently widespread speculation surrounding the 21-year-old, with a number of the world's biggest clubs said to be interested in his signature.
Liverpool, Chelsea and Manchester City are all being credited with an interest in the Georgia international, who made the move to Napoli from Dinamo Batumi over the summer.
Emile has said that there is no chance of his client leaving the Italians in January, but a transfer could be possible next summer if an offer in the region of €100m (£86m) were to arrive.
"You know what's crazy, he's done what he's been in doing in Russia and Europe for the past couple of years," he told Fabrizio Romano's YouTube channel.

"He's come to Napoli, he's been brilliant, and people are talking about €100m (£86m). For me, if he continues to perform like this till the end of the season and next season, because there's a zero per cent chance they sell him [in January]. He will reach €100m (£86m) for sure."
Kvaratskhelia has scored eight goals and registered 10 assists in 17 appearances for Napoli this season, including six goals and seven assists in 12 Serie A matches.
The attacker has also been in strong form in the Champions League, contributing two goals and three assists, with Napoli finishing at the top of their section ahead of Liverpool.
Kvaratskhelia represented Rubin Kazan between 2019 and 2022 ahead of a switch to Dinamo Batumi, departing the club earlier this year following Russia's invasion of Ukraine.

The attacker signed a five-year deal with Napoli upon his arrival, but there have been reports that the Italian side are keen to hand him fresh terms due to his form this season.
Kvaratskhelia's father, though, said that the club had not yet been in touch to offer a new contract.
"Nobody has spoken to us about the contract yet. At this stage, Khvicha doesn't even think about it, he only thinks about playing. Khvicha is informed about market rumours, but it doesn't influence him at all," Badri Kvaratskhelia told Imedi TV.
The forward played 83 minutes of Napoli's Champions League clash with Liverpool on Tuesday night but could not prevent his side from suffering a 2-0 defeat at Anfield.

After the match, Reds boss Jurgen Klopp branded Kvaratskhelia "a good player" when discussing his battle with Trent Alexander-Arnold.
"He's a good player. Both are good players, so it's a really difficult one. I know people will talk about one or two situations when Trent tried to be in front of him and the ball goes through," said Klopp.
"But he is really good, the boy, and really quick and you have to defend him together in these moments. When he has the advantage of the first movement, then he is already gone.
"You have to try to be there in the moment when the ball arrives, but if you cannot do that then you need to be protected because he has speed, he is cheeky, he goes inside, he can go outside, that makes it always really difficult.
"A good player and I thought Trent played a really good game against him, was really on fire, didn't get frustrated by one or two situations where he was second-best, stayed in the game and I liked Trent's game tonight."
Kvaratskhelia starred in Napoli's Serie A clash with Sassuolo last weekend, scoring once and providing two assists in a 4-0 victory for the Blues.
