Bayer Leverkusen are assessing the market for Konstantinos Karetsas. Genk's technical director, Dimitri de Conde, stated that it would be a dream to keep Karetsas for another year but the chances are not great. The club's CEO, Luc Huibregts, clarified that the motivation for a sale is not purely financial but concerns the player's development. Karetsas has a contract until 2029 and a market value that reaches 28,000,000 euros. Genk will not allow him to leave unless they are fully satisfied.

Bayer Leverkusen consider Konstantinos Karetsas a potential successor for the number ten role. Club officials believe his profile is a perfect fit for their high-tempo, possession-based style.

According to Kicker, Bayer Leverkusen has a strong interest in Kos Karetsas. The German vice-champion could sign him during the summer for the number ten position.

Bayer Leverkusen sent scouts to observe 18-year-old attacking midfielder Konstantinos Karetsas, with Het Laatste Nieuws reporting they were one of 23 clubs present. Other teams with scouts at the game included Borussia Dortmund, AS Monaco, AC Milan, and Manchester City, who have reportedly been following the player for a while. KRC Genk recently extended Karetsas's contract and wants to keep him for another season, but hopes to eventually secure a fee significantly exceeding 30 million euros to make him their most expensive transfer ever.
