Kalidou Sidibé

In January 2026, reports cited a Transfermarkt market value of €1.8 million. Earlier, in May 2025, Guingamp reportedly valued the player at £1.7 million (approx. €2.0 million), with Celtic said to have bid that amount. In March 2025, reports suggested Celtic was willing to pay nearly £2 million (approx. €2.3 million). His most recent completed transfer was from Quevilly Rouen to Guingamp in August 2023 for a fee of €700,000.

Our valuation is driven by Kalidou Sidibé's expiring contract, which significantly discounts the reported valuations from mid-2025. While figures around €2.0 million were mentioned when he had over a year on his deal, the current price reflects the leverage buying clubs have with only six months remaining. The range is anchored by his last transfer fee of €700,000 and the reported interest from multiple clubs, which should ensure a fee above a nominal amount.
