Hate to say it, but who cares what the other players think? It’s a business, and part of that business is supply and demand. If you can supply something few others can, you will be in high demand. Demand creates inflated wages.
Maybe KDB could have made more money if he had said, “Nah, I’d like to leave on a free and go to Madrid, where they’ll pay me €500K/wk,” but he didn’t. Why?
His choice to accept the money.
If someone else comes along and negotiates a better deal, to which City agrees, then there’s valuable information in that.
Maybe City doesn’t value you?
Maybe City values you less or him more?
Maybe City pushed the boat out because he’s a generational talent that could help win literally everything?
Maybe the level of wages has just ratcheted up another notch because that’s the nature of the business and why you got your €350K/wk in the first place?
Whatever the reasons, there are always going to be some players in every locker room, and employees in every office, making more than others. From there, each employee has a personal choice to make, and each business has to live with any disharmony it produces.
That said, I’m never in favor of a player attempting to bend City over, or unsettling the team, and I think there is often supreme talent that is bubbling under the surface elsewhere waiting to be discovered, and it can save £100Ms.
