The 20 biggest football agents, their clients and their source of income

18) Darren Dein

Darren Dein is the son of former Arsenal chairman David Dein and is an unpopular figure among the Gunners as he engineered the exits of Cesc Fabregas, Robin Van Persie, Emmanuel Adebayor, and Gael Clichy from Arsenal.

He still represents Cesc Fabregas, Gael Clichy and, Alex Song, who recently moved to Russia from FC Barcelona. Dein was also a close aide of Thierry Henry and was the best man at his wedding.

17) Grupo Santos Idub

Xabi Alonso is one of the high-profile players to be represented by Grupo Santos Idub

Grupo Santos Idub is another major footballing agency which boasts a client roster that contains the names of Xabi Alonso, Samuel Eto'o and Mikel Arteta. Samuel Eto’o, who was once the highest-paid footballer in the world with Anzhi Makhachkala, is one of their most important clients.

Incidentally, Euro 2016 star Antoine Griezmann was also represented by them a while back before the Frenchman decided to axe the agency.

That would have come as a major disappointment to them since Griezmann is being mooted with a high-profile move away from the Vicente Calderon next season. Even then, Grupo Santos remains a major player in the field of football agents.
