You can’t blame De Gea for missing the penalty, there is always going to be a villain in a shootout. I’m surprised it got to 10-10. Maybe the only thing you can criticise De Gea for is he could have saved one?
I agree with you. De Gea is not to blame for the penalty he missed. Rulli could have missed the penalty also. These are goalkeepers in the end. De Gea could have scored also and another player could have missed a penalty. And yeah, I was really surprised that he couldn't even so close to save one. Rulli was the opposite and he was nearly saving 2-3 penalties. And I saw an interesting statistics that De Gea couldn't save the last 36 penalties.
