Stumbled across this on Twitter.
Here we have a former PL referee essentially admitting that the LOTG are applied in a manner that protects the game. It's therefor a reasonable assumption to make that he's inferring that they want to keep it 'entertaining' for the good of the game.
And just imagine, if they can do that in a single game, there is no reason to think they don't apply the same logic to a competition, perhaps even the Premier League? After all, we can't have a single team running away with it now, can we? It's not the 90's. Got to keep the competition 'interesting, or else the PL might start losing TV revenue.
