Who is the penalty killer among Casillas, Buffon, Cesar and Cech?

I think Cech is still not good at penalty kicks, and he is not very good at set kicks.

Buffon is better than Cech, but he is also good at flying balls

Cassie's performance in this European Cup is still good, but there is an element of luck.

Cesar is still good at saving penalty kicks, although he is not as famous as the above three.

The ranking is: Cesar-Cassie-Buffon-Cech (only for penalty kicks), but the one who is famous for penalty kicks is Ricardo~
