The Most Expensive Deadline Day Transfers in History

The 2026 summer transfer window in the major European leagues has closed, and its final day immediately reshaped the historical ranking of football’s biggest last-minute deals. Four transfers completed before the market shut broke into the all-time top 20, including one that matched the existing summer record.

Winsportsonline analysed the 20 most expensive transfers completed on the final day of a window. The most expensive move from this summer’s closing day was Enzo Fernández’s €145 million transfer from Chelsea to Manchester City, which matched Alexander Isak’s Newcastle-to-Liverpool move from 2025.

Fernández had already set the winter record when Chelsea paid Benfica €121m for him in January 2023. He has therefore become the first player in recent history to hold the record for the most expensive winter closing-day transfer while also sharing the summer record. Iliman Ndiaye, Matias Fernandez-Pardo and Ibrahim Mbaye also entered the historical top 20 with moves completed on the final day of the 2026 summer window.

Key Takeaways:

• Enzo Fernández became the first player in recent history to hold the winter transfer record and share the summer record after his €145 million move to Manchester City
• Four deals from the final day of the 2026 summer window broke into the all-time top 20, with Iliman Ndiaye, Matias Fernandez-Pardo and Ibrahim Mbaye joining Fernández in the ranking
• Manchester City completed two of those four transfers and now have four of the 20 biggest closing-day purchases in history, more than any other club
• Nine of the current top 20 were completed in 2025 or 2026, while 14 have taken place since 2023
• Premier League clubs were the destination in 16 of the 20 transfers, including all four new entries from 2026

The Most Expensive Deadline Day Transfers in History

Enzo Fernández holds the winter record and shares the summer record

Enzo Fernández now occupies a unique place in transfer history. Manchester City paid Chelsea €145m for the midfielder on the final day of the 2026 summer window, matching Liverpool’s €145m purchase of Alexander Isak from Newcastle one year earlier. The two now share the record for the most expensive transfer completed on the closing day of a summer window.

Fernández was already the outright winter record holder. Chelsea paid Benfica €121m for him in January 2023, while Jhon Durán’s €77m move from Aston Villa to Al-Nassr in 2025 is the next-most expensive winter deal in the ranking. The difference between the two stands at €44m.

Fernández is therefore the first player in recent history to sit at the top of both categories, sharing the summer record at €145m while holding the winter record outright at €121m.

Four 2026 deals break into the all-time top 20

The newly closed window changed more than just the record at the top. Three additional transfers from its final day also entered the all-time top 20.

Manchester City paid Everton €70m for Iliman Ndiaye, making him the eighth-most expensive player in the ranking. Newcastle signed Matias Fernandez-Pardo from Lille for €60 million, putting him level with Anthony Martial and Nico González, while Ibrahim Mbaye’s €55m move from Paris Saint-Germain to Aston Villa placed him alongside Brennan Johnson.

Together with Fernández, that means four of the current top 20 were added on the final day of the 2026 summer window. Including the previous year, nine of the 20 most expensive deals in the ranking were completed in 2025 or 2026.

Manchester City add two top-20 transfers in one day

Manchester City were responsible for half of this year’s new entries, signing Fernández and Ndiaye. Those two moves increased the club’s representation in the historical top 20 to four transfers, more than any other buyer.

Their previous entries are Matheus Nunes’ €62m move from Wolves in 2023 and Nico González’s €60m transfer from Porto in the 2025 winter window. Manchester United follow with three appearances through Antony, Anthony Martial and Manuel Ugarte, while Chelsea, Arsenal and Newcastle each have two.

All four of City’s entries have come since 2023, with two added during the window that has just closed.

Nine of the top 20 were completed in 2025 or 2026

The ranking has changed rapidly over the past two seasons. Nine of the current top 20 were completed in 2025 or 2026, while 14 have taken place since 2023. Only six transfers in the list predate that period.

That has pushed several former record deals further down the order. Gareth Bale’s €101m move from Tottenham to Real Madrid in 2013 once stood alone as the benchmark for a summer closing-day transfer, but it now sits behind Fernández and Isak at €145m. Fernández’s €121m winter move to Chelsea also ranks above it.

Fernando Torres’ €58.50m switch from Liverpool to Chelsea in January 2011 has dropped outside the top ten, while Anthony Martial’s €60m move to Manchester United and Pierre-Emerick Aubameyang’s €63.75m transfer to Arsenal have also been overtaken by newer deals.

The current top 20 now closes at €50m, the fee recorded for Manuel Ugarte, Thomas Partey and Galeno.

Premier League clubs bought 16 of the 20 players

Premier League clubs were the destination in 16 of the 20 most expensive transfers in the ranking, and all four newcomers from 2026 ended in England’s topflight. Fernández and Ndiaye joined Manchester City, Fernandez-Pardo moved to Newcastle and Mbaye signed for Aston Villa.

Only four of the 20 ended outside the Premier League: Gareth Bale’s move to Real Madrid, Randal Kolo Muani’s transfer to Paris Saint-Germain, Jhon Durán’s switch to Al-Nassr and Galeno’s move to Al-Ahli.

English clubs therefore account for 80% of the current top 20, continuing a pattern that has become even more pronounced with the latest additions.
