Efthymios Koulouris has been performing well at Pogoń Szczecin, catching the attention of other clubs. His estimated value ranges from 3.5 to 4 million euros according to Dariusz Adamczuk, the sporting director of Pogoń Szczecin. Kamil Grosicki humorously suggested that Koulouris should be priced at 5 million euros. There is a consideration for outgoing transfers in the winter, and Koulouris is regularly linked with a move due to his performance. His contract expires at the end of June 2026.

According to the portal meczyki.pl, FC Seoul is interested in Efthymis Koulouris.

The financial difficulties faced by Pogoń Szczecin have led to discussions about selling players, including their best striker, Efthymis Koulouris. The club's financial issues are highlighted by debts amounting to approximately 53 million złotys, with 2 million owed to football agents over the past two years. As a result, there is a looming threat of a player sell-off to manage these debts.

Efthymis Koulouris, a Greek striker for Pogoń Szczecin, is a co-leader in Ekstraklasa's top scorers list with 11 goals this season. Panathinaikos Ateny, interested in strengthening their forwards, may hinder his top scorer bid as they eye a transfer. The potential fee is around 2 million euros, but Pogoń could ask for more. Koulouris has scored 44% of Pogoń's league goals this season. Previously, he was the top scorer in Greece with 19 goals for Atromitos in 2018/19, leading to a 3.5 million euro move to Toulouse.
