Connected with Major Clubs
Transfermarkt has revised the market values of 388 players in the Greek Super League this December. This division has gained a reputation for cultivating exceptional young talent in recent years. Brighton paid Olympiacos €35 million for striker Charalampos Kostoulas during the summer, while forward Stefanos Tzimas is also now a Seagull, following a transfer from PAOK for €18m by German club Nurnberg. We spotlight three promising young stars currently making waves in Greece, who have all received value upgrades this winter. This includes the winner of the Golden Boy Web award, along with insights from TM’s Greek expert on the latest upcoming talents.
Christos Mouzakitis – The Golden Boy Web Winner and League MVP
Christos Mouzakitis is one of Greece’s brightest young talents, recently crowned ‘Golden Boy Web’ 2025 winner by Tuttosport after a global fan vote. His market value has surged from €15m to €25m this December, making him the biggest benefactor of this update and the most valuable player in the entire Greek Super League. Nikos Sofis, Transfermarkt’s Area Manager for Greece, shares his thoughts on the Olympiacos prodigy: “Mouzakitis has undoubtedly garnered significant attention due to his performances, the maturity of his play at such a young age, and his selection for the national team. Winning the Golden Boy Web award adds to his accolades.”
“It’s no surprise that the top clubs across Europe are interested in him. Though he primarily plays as a central midfielder, he is versatile enough to play defensively or join the attack. His humility is remarkable, and I believe he will maintain this quality throughout his career. Consequently, there are no limits to what he can achieve, and he appears destined for a top club.” Mouzakitis is now listed as the joint-10th most valuable U18 player globally.
Giannis Konstantelias – ‘The Greek Messi’
Another noteworthy rise in value comes from PAOK’s attacking midfielder Giannis Konstantelias. The 22-year-old’s market value has increased from €17m to €20m, positioning him as the second most valuable player in the league, just behind Mouzakitis. Sofis elaborates on the PAOK star: “Dubbed the ‘Greek Messi’ by some media outlets, Konstantelias is an exceptionally skilled player who consistently finds solutions in the attacking third. His talent is highly coveted, and while he has attracted interest from major European clubs, he chose to extend his contract with PAOK until 2029.”
Konstantinos Tzolakis – A Goalkeeper with Bright Prospects
Young goalkeeper Konstantinos Tzolakis is starting to draw significant interest from top European leagues. The 23-year-old Olympiacos shot-stopper sees his value rise by €2m to €15m. Sofis offers further insights: “Tzolakis possesses immense talent and potential. He needs to refine his decision-making, as he has had moments that led to conceding goals. However, at times, he can be virtually unbeatable. If he can minimize his errors, a bright future awaits him at a top club or league in Europe, and there is already interest in his abilities.”
Understanding Transfermarkt’s Market Values
Transfermarkt calculates player market values using a range of pricing models. A critical factor is the Transfermarkt community, whose members engage in detailed discussions and evaluations of player values. It’s important to note that these market values should not be confused with actual transfer fees.
The goal is to reflect a player’s projected value in an open market. Various individual transfer modalities and situational conditions play a significant role in determining these values. For more details on our methodology, please refer to our comprehensive market value definition.
