Messi will only score PKs if the goalie decides to randomly jump the wrong way, and when he does we make an abstract afterthought of "wow, nice feeling".
He might be the best offensive player out there overall, but he is still one of the worst at PKs and its amazing he still takes them in this team where almost every other player could do a better job. It might have something to do with him scoring as many goals as possible, but if he still strikes them when it really mathers im confused.
