Off course you have to put this in to context. It's not about going from average to worldclass, your DNA and talent sets your limitations. But at this level only the smallest improvement can make the difference.
Another way to look at it is to compare the first touch of Wayne Rooney on and off form. On his bad days it's sometimes horrible, IMO probably a combination of physical insecurity and poor timing. Then a couple of days later he looks like a different player. Tell me otherwise what create this differences if not practice who improves your timing?
TBF I find the critics regarding Embolo's technique a little bit over exaggerated.
