The negotiator who crushes everyone runs out of people to deal with
When I was coming through the agent ranks, I worked with one of the best agents in the game at the time.
He was hyper-aggressive with clubs. Every clause was a fight, and for quite a few years the strategy held together well: he got the best deals, so he got the best players, and because he had the best players the clubs had to deal with him whether they liked it or not.
What he didn't realise until it was too late was that those clubs were keeping score.
It started with one club. They refused to deal with him, and accepted they wouldn't get to sign any of his players as the price of that. Which held until some of his players wanted to go there. They couldn't go through him, so it became their problem rather than his, and they solved it the only way open to them: they terminated with him and did the deal with the club direct.
That was the crack in the veneer, and the other clubs spotted it. They saw the opportunity to put him up against the ropes and thought the trade-off was worth it, even where it cost them a shot at that top tier of players. With fewer clubs prepared to deal with him he couldn't offer the full service of an agent, players started doing deals themselves, and just as quickly as he'd come up he unravelled and was out of the game completely.
That version takes years, but I've seen someone butcher it in one night:
I've sat in a training ground the day before deadline day, translating for an agent who argued every clause until after midnight and fought hardest of all for his own fee to be paid up front. When the medical came back a 50/50 call the next morning, the club walked away, and the sporting director told me afterwards that they'd read the man across the table and decided they didn't want him in the building slamming his fist on the table for more money every few months for the next 4 years. The agent thought he was doing right by his player, but the reality was that his inexperience torpedoed the deal.
The real skill in negotiation is optimising the deal without burning the bridge.
Because you have to remember that you're dealing with humans who have emotions and long memories, and every move you make, from how you handle your wins to your losses, is being weighed against whether they want to see you again.
The part of negotiating big deals that gets vilified is the big agent fee that comes with it. Agents' fees are proportionate to the player's salary, so big deals carry big fees. That's the model, it's how I built my career (fewer deals, bigger ones), and no player should be steered off a big contract because of it.
The damage comes from agents fighting for the fee harder than they fight for the player's terms. Not only is it unethical, it's short-sighted. The fee should grow commensurate with the size of the deal you negotiated, not at the expense of it.
The other negotiation reality is that the calendar works against you: you can negotiate a 3-year deal, and the player will think it's the best deal ever in year 1, at the level of what he should have been paid in year 2, and by year 3 he's decided he should have been paid more all along. Memories of the circumstances are short.
The strategy I use is to be ruthless in a negotiation, but always inside my own values: never rude, never unprofessional, never unethical. Part of that is principle. Part of it is arithmetic, because no single client brings in more than a few percent of International Sports Consulting's revenue, and no deal is worth risking the other 97% for a bad reputation.
💡 Lesson: a club can lose every clause and still say no, because what it's really deciding is whether it wants you and your player around for the next few years.
