The Biggest Signings in Turkish Football for the 25/26 Season

Investment in Turkish teams has increased significantly in recent years, thanks to the greater visibility of the national tournament and the competitiveness that drives teams to seek major reinforcements. For the 2025/2026 season, there have been some big signings, including the most expensive in the country’s history.

Here, we have listed the main signings made by Turkish teams for the 25/26 season. This will give you a better overview of the squads, help you understand the title favorites, and make more informed bets at 1xBet.

Victor Osimhen

Without a doubt, the biggest highlight of the Turkish transfer window was the permanent signing of 26-year-old Nigerian Victor Osimhen by Galatasaray from Napoli. He already played for the Turkish team last season, but was on loan from the Italian team.

When Osimhen arrived at Galatasaray, the entire football world was surprised. After all, he had led Napoli to great glory and was considered one of the best strikers in the world at the time, being sought after by major teams. However, after disagreements with the Italian team’s management, he ended up losing his place in the team, and in a last-minute move in the transfer window, he was loaned to Galatasaray.

Evidently, he stood out and excelled in the team, greatly increasing the quality of the squad. As a result, Galatasaray paid €75 million to sign him permanently, making it the biggest purchase in the history of Turkish football. What is even more striking is the difference in value compared to the other most expensive signings in the league, as Osimhen is almost three times more expensive than the second most expensive signing.

In addition to the impact on Turkish football, Osimhen’s signing also made headlines across Europe, as it was the sixth most expensive signing of the entire transfer window, behind only purchases made by English Premier League teams. Here is the list of the top 10:

• Alexander Isak, from Newcastle to Liverpool for €150 million.
• Florian Wirtz, from Bayer Leverkusen to Liverpool for €115 million.
• Hugo Ekitike, from Eintracht Frankfurt to Liverpool for €79.8 million
• Benjamin Sesko, from RB Leipzig to Manchester United for €76.5 million.
• Bryan Mbeumo, from Brentford to Manchester United for €75 million
• Victor Osimhen, from Napoli to Galatasaray for €75 million
• Nock Woltemade, from Stuttgart to Newcastle for €74.8 million.
• Matheus Cunha, from Wolverhampton to Manchester United for €72.3 million.
• Luis Díaz, from Liverpool to Bayern Munich for €70 million.
• Emerichi Eze, from Crystal Palace to Arsenal for €69.3 million.

Little by little, the high investment made in the Nigerian striker is already paying off. One example is Galatasaray’s surprising victory against Liverpool in the Champions League, with a goal scored by Osimhen.

Wilfried Singo

The second biggest signing of the Turkish transfer window is also from Galatasaray. It is 24-year-old Ivorian right-back Wilfried Singo, who was signed from Monaco for €30.7 million.

Singo stood out for the French team last season, justifying the amount paid by Galatasaray. For Monaco, he played in 60 games over two seasons, scoring four goals and providing four assists. However, the modest numbers do not reflect the athlete’s defensive strength, which was the main reason for the Turkish team’s purchase.

The right-back is also a guaranteed presence in the Ivory Coast national team, having won the Africa Cup of Nations with his team in 2023. It is worth noting that in addition to the initial transfer fee, Monaco will still be entitled to receive 10% of the profit from a future sale of the player.

Orkun Kökçü

Orkun Kökçü, a 24-year-old midfielder, is the most expensive Turkish player ever acquired by a local team. He is currently on loan at Besiktas from Benfica (Portugal), but the contract stipulates that the player must be purchased for €30 million in the next season transfer window. For this reason, he can already be considered one of the big signings of the current window.

The athlete stood out playing for Feyenoord, which led Benfica to buy him for €29.7 million. However, one season later, Kökçü arrived at Besiktas to play for the first time in a team in his home country. For this reason, expectations are high.

Kökçü had excellent statistics at Benfica, which easily justifies the investment made by Beşiktaş. In total, he played in 98 matches, scoring 19 goals and providing 22 assists. In other words, an average of more than one goal contribution every three games. His good performance also helped the midfielder establish in the Turkish national team.

Uğurcan Çakir

Another Turkish player on the list, Uğurcan Çakir became the most expensive goalkeeper in the history of the Turkish league. Galatasaray, in need of a reliable player for the position, paid €27.5 million to sign him from Trabzonspor. The amount is noteworthy not only because of the player’s position, as goalkeepers are not usually so expensive, but also because of Çakir’s relatively advanced age, as he is 29 years old.

According to Transfermarkt, a website specializing in the football market and transfers, Çakir’s market value is well below the amount paid by Galatasaray: only €15 million.

Kerem Aktürkoğlu

Turkish striker Kerem Aktürkoglu, 26, has already moved a lot of money throughout his career. In 2024, he left Galatasaray for Benfica in Portugal for €15 million. Now, a year later, he has left the Portuguese team and been signed by Fenerbahçe for €22.5 million.

The presence of so many Turkish names on the list of the most expensive signings in the country is a great indication that the current generation of athletes is promising. Thus, clubs are spending large sums on local players instead of on foreign stars.

The signing drew even more attention due to the fact that Aktürkoglu has a good history at Galatasaray, Fenerbahçe’s rival. There, he played 179 games, scoring 46 goals and providing 42 assists, with an incredible average of goal involvement. At Benfica, the numbers were also good: in 58 games, he scored 17 goals and provided 13 assists.

Dorgeles Nene

Mali’s right winger Dorgeles Nene is only 22 years old, which explains Fenerbahçe’s €18 million investment to sign him from RB Salzburg. Considered a promising young player, Nene has already scored eight goals for the Malian national team and is one of the African country’s biggest stars.

Even though he stands out for his enormous skill, which does not translate into numbers, Dorgeles Nene achieved excellent statistics for RB Salzburg. In 88 games, he scored 22 goals and made 15 assists.

Ederson

Brazilian goalkeeper Ederson made his mark at Pep Guardiola’s Manchester City, being the undisputed starter in virtually all of the English club’s recent major achievements, including the Champions League in 2023. He stood out not only for his saves but also for his quality with the ball at his feet, which always helped a lot in building up the team play.

However, at 32, his era at Manchester City came to an end and the athlete’s destination was Fenerbahçe, who paid €11 million to have him on their roster. In total, he played 372 games for Manchester City. It is worth remembering that in 2024, he was voted the best goalkeeper in the world by FIFA, which shows the magnitude of the impact of this signing, even more so considering the low transfer fee.

Milan Skriniar

Experienced Slovakian defender Milan Skriniar has played for several giant clubs in his career and was at Paris Saint-Germain. However, he was not a starter for the French team. Therefore, now at the age of 30, he also signed with Fenerbahçe, which paid PSG €6 million to have him on the roster. With that, he became one of the main defensive reinforcements of the Turkish transfer window, in yet another great deal due to the amounts involved.

Nélson Semedo

Another very experienced player who has played for big clubs and signed with Fenerbahçe is Portuguese right-back Nelson Semedo. He began to stand out in football, playing for Barcelona and then transferred to Wolverhampton in England.

It is noteworthy that the transfer was at no cost, as he signed with the Turkish club after his contract with the English team ended. In this way, Fenerbahçe once again showed that it is very attentive to the market.

Marco Asensio

Another player who left Paris Saint-Germain for Fenerbahçe was Spaniard Marco Asensio, who had a remarkable career at Real Madrid between 2016 and 2023, winning three Champions League titles with the Spanish team.

However, he never managed to establish himself at PSG and was recently loaned out for a short period to Aston Villa in England. Fenerbahçe paid €7.5 million for the player.

Tammy Abraham

Striker Tammy Abraham emerged onto the football scene with high expectations of becoming one of England’s great center forwards while playing for Chelsea. His height (1.94m) has always attracted a lot of attention. However, he never established himself in the world of football, and after Chelsea, he played for Milan and Roma before being signed this year by Besiktas for €13 million.

So far, Abraham is performing incredibly well for the Turkish team: in 13 games, he has scored 8 goals and provided 2 assists. That is, almost one goal contribution per game.

Andre Onana

Andre Onana was once considered one of the best goalkeepers in the world while playing for Inter Milan, which led Manchester United to pay more than €50 million for him in 2023. However, he ended up not establishing himself in the English team.

He has now arrived on loan at Trabzonspor. The contract runs until June 2026. If they want to keep him in the squad after the loan ends, the Turkish team should already be aware that the player’s estimated market value is €20 million.
