Roy Hodgson's agent, Leon Angel, was warned by Fifa about his future conduct after breaking rules in a transfer involving the Brazil keeper Heurelho Gomes, reports The Guardian.
The case was referred by the English Football Association to Fifa in June 2011. Less than a year later, Angel worked with the FA to help negotiate Hodgson's contract to become England coach.
Fifa's disciplinary committee fined Angel £4,840 and ordered him to pay costs for the disciplinary process.
Fifa said it warned Angel that a further breach "will result in more severe sanctions … even a withdrawal of the players' agent licence".
