Why? A young 'generational talent' would be in the early days of his career, and be paid great money to play in a team guaranteed to compete in the CL as long as QSI is there to foot the bill (who knows what happens after a few years of the Qatar WC). As long as you're not signing a ridiculous Harry Kane contract, there's no issue. This won't stop anything, and the marker they're putting down from here on out could be decisive in actually increasing the chances of that happening.
Imagine that, honoring your contract. Whether they want to sell or not after that is their prerogative.
