Live updates on transfer rumours.
TransferFeed valuation based on market analysis.
Most recently, in November 2026, reports indicated Grêmio's asking price is between €12 million and €15 million, with his Transfermarkt value cited as €5 million. A few months prior, in September 2026, Shakhtar Donetsk was reportedly preparing a €7 million offer before the move was halted by an injury; his market value was then noted as €4 million. In December 2025, Beşiktaş was linked with a €3.5 million offer, while his Transfermarkt value was listed at €3 million.
Our valuation for Gustavo Martins is driven by the most recent reports from November 2026, where his club Grêmio is demanding a fee between €12 million and €15 million. This figure is strongly supported by reported interest from two Premier League clubs, which suggests a final fee will be close to the asking price. While earlier reported interest from Shakhtar Donetsk (€7m) was lower, the player's positive trajectory and current competitive demand justify a valuation within Grêmio's stated range.
