Thierno Ballo

In July 2026, reports stated a deal with Saint-Étienne was complete for a transfer fee of 'around' or 'over' €3 million. In June 2026, Millwall reportedly failed to reach an agreement on a permanent transfer, with their buy option cited as being either £3 million (approx. €3.5 million) or €3.5 million, a figure they deemed too high. His Transfermarkt value was noted as €6.00m in June 2026. A year prior, in July 2025, it was suggested a transfer to Rangers could command a fee slightly exceeding his then-market value of €5 million.

Our valuation is driven by strong, recent reports from July 2026 indicating a completed deal for Thierno Ballo to move to Saint-Étienne for a fee of approximately €3 million. This figure is corroborated by multiple sources, including the club's coach and the player's agent. This is further supported by Millwall's recent failure to activate a buy option valued at €3.5 million, which they considered too high, effectively capping the upper end of his current market value.
