Guilherme Arana

In December 2025, reports concerning interest from both Fluminense and Olympiakos repeatedly cited Guilherme Arana's Transfermarkt market value as €7.00m. The only historical fee mentioned in the available data is his permanent transfer from Sevilla to Atlético Mineiro in July 2021 for €2.5M.

Our valuation for Guilherme Arana is primarily driven by the reported agreement for his purchase by Fluminense and the consistent mention of his market value around €7 million. His status as a Brazilian international and his long-term contract until 2027 give Atlético-MG a strong negotiating position, suggesting a fee in this range is realistic.
