Very difficult to ban agents. Everybody is entitled to have help with negotiation. The best solution is to regulate their fees: 1.By outlawing all payments by clubs to agents acting for a player. The player should pay for his agent. No acting for both sides. 2. If an agent is genuinely acting for a club to get a sale, a written agreement should be lodged stating the fee payable by the club. In that case the agent could not be paid by the player or the buying club. 3. Fees subject to maxima. I realize there are tax implications and that all regs can be cheated on, but some regulation is better than none. Good luck FIFA.
