La Liga
Sergio Martínez, a 19-year-old midfielder from Racing de Santander, has entered the Real Madrid's transfer agenda for the final stretch of the market. The white club has already expressed interest to the Cantabrian team and is looking to reach an agreement for a player with a €3 million release clause.
The move keeps the possibility of another signing open, even though José Mourinho believes his squad is complete. Martínez is under contract until June 30, 2029, and his debut in LaLiga has accelerated a career that has also attracted interest from Barcelona and Villarreal.

Sergio Martínez Enters Real Madrid's Plans
The interest in Sergio Martínez goes beyond mere observation. According to José Félix Díaz, Real Madrid has already informed Racing of its intention to reach an understanding regarding the midfielder before the market closes.
The operation is constrained by a specific figure: his release clause is only €3 million. While Madrid could trigger it, the priority is to negotiate directly with the Cantabrian team and agree on the exit conditions.
Martínez renewed his contract in November 2025 and is tied to the club until 2029. His progression has been remarkably swift: just seven months ago, he was still part of the youth team and now he is part of Racing de Santander's first team.
His debut as a starter in LaLiga sparked further interest. On August 16, against Villarreal at El Sardinero, he scored with a shot that reached 126.7 km/h, according to competition data.
At 19 years and 93 days, he became the youngest player from Racing to score on his debut in La Liga in the 21st century. Before this season, he had already played 13 matches between the Second Division and Copa del Rey with the first team.

Racing de Santander Must Decide the Player's Future
The contractual situation requires Racing de Santander to make a decision. The €3 million clause was set before his breakthrough in the top division, and different clubs had made moves for Martínez even before his La Liga debut.
Barcelona and Villarreal had already inquired about him previously. The player had chosen to stay in Santander then, but his definitive step up to the first team and his first match in LaLiga have altered the landscape in the final weeks of the transfer window.
If the signing is completed, the next sporting step for Sergio Martínez would still need to be decided. One option could be to include him in Castilla to compete with the reserve team; alternatively, to keep him registered with the second team while working regularly under José Mourinho's guidance.
There is also the possibility of reaching an agreement that allows Martínez to remain on loan at Santander. This approach would guarantee him playing time in La Liga after starting the season as a first-team regular under José Alberto López's management.
The deadline necessitates accelerating discussions. Real Madrid aims to secure Sergio Martínez before other clubs progress and will need to decide in the coming days whether to negotiate the transfer with Racing or use the €3 million clause to facilitate the deal.
