It wasn't hit with power and was in the single most saveable spot in the goal. Slow = down the middle or bang in the corner, or its extremely saveable, power, pretty much anywhere but still best as far away from the keeper as possible. Half way between the keeper and post is stupidly saveable especially when not hit with major power. If a goal keeper doesn't dive far, he'll still easily reach it, if the gk dived for the post, it will still hit his body/legs most likely, it was a very very poor penalty, one that screamed no confidence(slow and not risking going over or past the post).
