See, I said smash it but I'd go for placement myself. Reason being, I'm very good at penalties (for my ability level) and I'm confident of putting the ball in the side netting where the keeper won't get it even if they go the right way.
I usually call goal or miss from those run ups too btw, often easy to tell.
it depends on the player for sure.
you could tell some rarely if ever took pens.
the best takers have the same run up whichever side they hit it and can just close the foot off to roll it other side.
They know where it's going but can change it if the keeper looks like he is going down early in the right direction.
then the best keepers can stand up and force player to take good pen
a bad keeper can make a lot of very average pens look good.
there was at least two decent to good pens saved by Croatian keeper. so he mad big difference.
