Boulaye Dia

In August/September 2026, reports on a move from Lazio to Rennes cited a total deal value between €8M and €11M, though Lazio was reportedly demanding €15M initially. In August 2026, Lazio's president was said to have previously evaluated offers around €18M, and Transfermarkt's value was listed at €5M. The player completed a transfer from Salernitana to Lazio in July 2026 for €11.3M. Earlier, in May 2025, he was reportedly valued at approximately €15M. His permanent move from Villarreal to Salernitana in July 2023 was for a fee of €12.0M.

Our valuation is driven by the very recent and concrete transfer data for Boulaye Dia. His completed move to Lazio in July 2026 for €11.3M provides a strong upper benchmark, while the immediately subsequent transfer negotiations with Rennes in August/September 2026 consistently report a total package valued between €8M and €11M. This tight cluster of recent, real-world figures provides high confidence in our estimate.
