Nottingham Forest and Everton eye Grêmio defender Gustavo Martins amid €15m valuation

Nottingham Forest and Everton are reportedly monitoring Grêmio centre-back Gustavo Martins ahead of the January transfer window.

According to German publication Fussballeuropa, both Premier League clubs have identified the 24-year-old Brazilian as a potential defensive reinforcement.

Grêmio are reportedly seeking between €12million and €15million for Martins, although previous Brazilian reports suggested he could be available for considerably less.

Neither Forest nor Everton have been reported to have submitted a formal offer.

Martins has established himself in Grêmio's senior squad after joining the club's academy in 2018.

The 1.91-metre defender has made more than 100 first-team appearances and developed a reputation for combining physical strength with mobility.

He has also contributed in attack, recording three goals and two assists during the 2026 campaign.

According to Fussballeuropa, Martins is open to experiencing football outside Brazil, with Forest and Everton monitoring his situation.

However, the reported asking price could become an obstacle.

While the German publication values a potential deal at €12–15million, Globo Esporte reported in September that the player's representatives believed offers starting at €5million could facilitate a departure.

The difference makes Grêmio's current negotiating position uncertain.

Martins previously attracted interest from clubs in other markets, including the United Arab Emirates, but no transfer materialised.

Martins remains under contract with Grêmio until December 2027.

In September, Brazilian newspaper GZH reported that the club had opened discussions over a proposed three-year extension.

However, a subsequent report revealed that Grêmio had paused contract renewal negotiations while prioritising their position in Brazil's top flight.

There has been no confirmation that Martins has signed a new agreement.

The defender also recovered from a minor thigh injury during August before scoring twice against Chapecoense in a 3-1 victory.

For Forest and Everton, his contract status and Grêmio's valuation could prove decisive if their reported interest develops into negotiations.

At present, the Premier League clubs remain linked with Martins rather than confirmed bidders.
