With the exception of the goalkeeper having his team's trust, the merit points you make can be either fully or partially explained by a PED doping program.
They have team togetherness because the doping means they have more energy and need fewer players. Ergo, the players are more familiar with less rotation.
They know their individual jobs. But if a shit point you make here but, again, if your job is to run like fuck for 90+ minutes without tiring then doping would help.
They work hard. Need I unpack this one for you? You should be getting the gist by now.
They are fast on the counter attack. Hmmm, wonder why?
Vardy is a good finisher. Yes he is. But his ability to get into spaces and run the fuck out of the channels and in behind defenders is best understood in the context of a club-wide doping program.
I'm afraid it's much more plausible than simply subscribing to the idea that the stars have aligned for them. I know people don't like the suggestion of cheating going on in the game, especially the English game, but it reeks of it this year with Leicester.
