People often jump with their arms raised, Mohsni has every right to raised his arms. If I use my body to shield the ball from a player, am I impeding them? Nope, I'm playing smart and to my advantage. The keeper had no intention of 'clearing the ball' but rather, if you cared to watch, attempted to catch the ball whilst an opponent was contesting for it. The keeper was at fault for his hesitation. To say that he was impeded is majorly clutching at straws.
