Just wondering !!!

im just wondering why it always has to be kaka who shoots the panalty always him, him him !!!!!
i mean for exampel this season not to mention most of last season every singel panalty we had kaka was the one who shoots.... well hellllo there are athor players who actually have 2 legs and knows how to shoot a ball !!!!
i think the athor players should giving the trust to do it, instead of Consecrating on kaka !!!!!
P.S: i was wondering about this for aquite a while and it nothing to with him missing the panalty today !!
