If 23-year-old Greek goalkeeper Konstantinos Tzolakis maintains his current level of performance at Hull and with the national team, his sale price will be between 60-80 million euros. Olympiacos has a resale percentage of 15-20%, meaning the Greek club could receive 12-15 million euros if a final transfer reaches that level. The excellent performances of the young goalkeeper, who has 13 caps for Greece, are continuously increasing Olympiacos' future financial expectations. Tzolakis joined Hull City from Olympiacos in August 2026 for a reported fee of €23.3 million and is under contract until 2031. In October 2026, reports indicated Hull City set a valuation of £40 million (approximately €47 million) for the player. His current market value on Transfermarkt is €18.00m. Liverpool has been recently linked with him.
