Sebastian Tounekti

In January 2026, Hamburg reportedly had multiple bids rejected by Celtic, with figures cited around €11 million, €13 million, and up to £11.3 million (~€13.3 million), although one report questioned the accuracy of these numbers. His Transfermarkt value was noted as €4.0 million around the same time. This followed his completed transfer from Hammarby to Celtic in September 2025 for a reported €6.4 million. Prior to that move, in August 2025, Hammarby had rejected bids from Celtic reportedly ranging from £2.6 million (~€3.1 million) to almost £4 million (~€4.7 million). In February 2025, he moved from Haugesund to Hammarby for €1.2 million.

Our valuation for Sebastian Tounekti is driven by Celtic's firm rejection of multiple bids from Hamburg in January 2026, reportedly reaching as high as €13.3 million. This occurred only four months after signing him for €6.4 million, indicating the club values him significantly higher than the rejected offers and their initial investment.
