Think I might be in the minority, but I'm quietly confident when Dusan steps up to take a pen. His penalties aren't always the most well placed like Rickies or MLTs, but equally he never looks like he's going to blaze it high and wide. So if you're consistently getting it on target, that has to up your conversion ratio. The trouble is, he plays in a position where he's often either a sub or subbed of. So...who takes the pens if he's not on the pitch? I think Morgan gets my vote.
Aguero tried placing his kick, low, with not enough power, should he have gone for hit hard and straight? Who knows?
