I'm sorry, but that doesn't make sense. What's the point in a player demanding a release clause linked to game-time if the minimum activated buyout fee is going to be at least 150% his actual value?
It's only beneficial for the player if the activated buyout fee is at or below his value, otherwise no clubs would be interested in him even in the case of the clause being activated - he'd be going nowhere no matter how many games he's played because who's gonna want to pay upwards of 150% market value for him?
It only works if, like Thiago, the player negotiates a clause activated release fee related to game time which is well below his actual value; otherwise it's no incentive whatsoever to the club to get him playing games.
The player's basically saying, "Don't play me enough, you lose me for half my value!". Such a threat becomes entirely idle when it's rephrased as, "Don't play me enough, you lose me and receive double what I'm worth!".
