Osimhen-led Super Lig break all-time Turkish record after busy summer

Turkish football has smashed its all-time transfer spending record after an unprecedented summer of signings.

At the heart of it all was Galatasaray’s record-breaking move for Victor Osimhen, which sent shockwaves across Europe.

Turkish football witnessed an unprecedented summer as Super Lig clubs splashed out $359 million (€421 million) during the 2025 transfer window, the highest in their history and eighth worldwide, according to FIFA.

Leading the charge was Galatasaray, who spent a record €148 million to reshape their squad. The headline signing was Victor Osimhen from Napoli for €75 million.

The Nigerian’s move from Napoli was the most expensive transfer ever completed by a Turkish club and the seventh-biggest worldwide this summer.

Galatasaray also added Monaco’s Wilfried Singo for €30 million and Trabzonspor’s Ugurcan Cakir for €27 million. Their investment ranked them 14th among all clubs globally, breaking both club and national records in the process.

While Galatasaray made the loudest statement, their rivals were not far behind in the summer transfer market.

Fenerbahce spent €87 million, the largest budget in their history, while Besiktas invested €38 million, also a club record, and Trabzonspor committed €24 million.

Together, the “big four” clubs accounted for 96% of all Turkish transfer spending, amounting to €297 million. Besiktas’s spending is set to rise further, with €38 million still due next season for the transfers of Orkun Kokcu and Tammy Abraham.

The window placed Türkiye firmly on the global transfer map, with their outlay contrasting sharply against the average per-player fee of €1.3 million compared to England’s €5 million.

Globally, transfer activity surged to an all-time high of $9.76 billion, led by the Premier League’s $3.19 billion.
