One thing that completely baffles me is that if a ball hits an attacker on the hand/arm, its handball and if htey score the goal is disallowed.

If the ball hits the same attacker but their teammate scores, it’s not handball & goal stands.

If the ball hits the defender then no handball either and they can clear it etc.

Same situation results in 3 completely different decisions. How?

Take the one on Saturday, it clearly hits cash on the arm (i dont think thats a penalty) but if the touch by Havetez is enough to deem it handball and disallow the goal then surely the touch by Cash on his arm is a penalty
