Inside the Big Six transfer circle - Which agents handle the biggest Premier League deals?

Football agents are not always viewed so favourably by managers, sporting directors and even the players they represent. But they are a vital cog in facilitating the multi-billion-euro transfer industry in every single transfer window and that is reflected by their huge earnings. The Premier League's top clubs, of course, need them perhaps more than any other league.

Liverpool splashed out €145 million on Alexander Isak, the largest transfer fee spent in the 2025 summer transfer window, while the Reds also brought in Florian Wirtz in a deal worth €125 million. Chelsea forked out €60 million for Joao Pedro, while Manchester United ploughed €225 million into revamping their strikeforce with Benjamin Sesko, Bryan Mbeumo and Matheus Cunha. Arsenal swooped for Eberechi Eze and Viktor Gyökeres, as well as Martin Zubimendi. It all comes at a huge added cost on top of the transfer fee and weekly salary.

According to the Football Association's recent figures, Chelsea spent €75 million on agent fees between February 5, 2025 and February 5, 2026. That is substantially higher than any other club, with Aston Villa next on the list with €44 million. Manchester City racked up €42.8 million in agency fees.

Liverpool - despite spending over €450 million in a record-breaking summer transfer window for an English club - managed to keep their agent fees down to €38.8 million, while fellow Big Six clubs Man United and Arsenal were on €36.4 million and €36.8 million respectively. But which agents are getting the most business and potentially the biggest slice of the pie when it comes to the high-profile deals?

Which agencies were most used by the Premier League Big Six?

Transfermarkt's extensive database comprises of over 13,000 registered agencies, with more than 18,000 licensed agents carrying their own profile on our website. Using this data, every deal that is entered into the system can identify which agents tend to be used by clubs when it comes to big-money signings.

Many would expect Jorge Mendes' Gestifute to be one of the leading powerbrokers in Premier League dealings, having worked closely with Chelsea and Manchester United in recent years. However, the Portuguese super agent's agency did not top the list for transfers across the 2025/26 season.

As the graphic above shows, Unique Sports Group, who represent Manchester City defender Marc Guéhi, have overseen eight deals in total. Family members are increasingly involved in modern deals as they are viewed are trustworthy figures, with five deals facilitated by those closest to players involving Big Six clubs. Also with five deals are American sports firm CAA Base - oversaw Eze's move to Arsenal - and AS1, who look after Piero Hincapié.

With that in mind, it's hardly surprising that players want to join the agencies that have a track record of dealing with big clubs. One deal might make the difference. But the published figures from the FA and Transfermarkt's own data can conclude that, no matter how football clubs and fans view agents in the modern game, their work is still viewed as essential to brokering the biggest deals.
