Every single molecule that is a key part of bioenergetic processes has a different calorie value per gram, and those are still just more precise estimates. Every single human can burn through these differently due to how their muscles work, how their cell mitochondria work, how the organisms in their digestive track interact with it, their liver, general availability of other components of the biologic processes, other processes making use of particular molecules... a whole host of factors.
What's more, a person's cell mitochondria can change in terms of optimal function for a variety of environmental reasons, including change in diet, not just a change in calorie intake.
It's really not, and I'm half tempted to see if you can even define what a calorie is.
You also have a minimum amount of fat you can consume, otherwise it becomes hazardous to your health. This assists with cellular function and hormone synthesis, fat-soluble nutrient uptake, to name a few.
He's listed as 86, which is just the 3 kgs above his junior weight, but I tend to agree that he's probably closer to 90kgs than that, say 88.
I think he doesn't need to lose any total muscle, just not work on his upper body quite so strongly. I think he'd play well enough at around 85kgs, but that's an indirect measure of the kind of physical performance you want to see from him. He needs to be a hair quicker, and he certainly needs to be more consistent in his first steps, and generally more economical with how he runs in open space, particularly when he's not going at 90%+ max.
