Remember that luck doesn't exist. It's a term used for out of the ordinary circumstances.
For example a shot going out for a corner that hits your player and goes in, a goal that should have been called offside, a penalty that was outside the box.
These are all examples of bad/good luck.
A shot that is on target that a defender deflects while trying to block isn't luck.
There has been a degree of good/bad luck all season. Is it the managers fault...it could well be the law of attraction.
While your lucks down, you get kicked.
Doesn't matter what the reason is.
Hitting the woodwork isn't unlucky, it was a miss!
Is McCarthy unlucky for having such a torrid time worh injuries?
Technically not. It must be down to the way he landed,twisted,got hit, diet etc etc.
But I would still class him as unlucky, same with Besic.
