The responsibilities of a football agent include which of the following?

The responsibilities of a football agent predominantly include representing clients during negotiations. This role is critical as agents act as intermediaries between players and clubs, ensuring that their clients' best interests are prioritized in contract discussions, endorsement deals, and other professional dealings. Agents leverage their knowledge of the market and existing relationships within the industry to secure favorable terms for players, helping them navigate the complexities of football contracts and maximizing their earning potential.

In contrast, hiring coaches for teams, marketing the team brand, and deciding players' training routines typically fall under the purview of club management and coaching staff rather than that of an agent. These responsibilities require a different skill set and a deeper involvement in team operations, which agents do not engage in as part of their primary function.
