Disagree. Nothing to do with positioning or footwork. The header looped up and hit the bar, something we have seen a million times, if you you are lucky, your defenders react quicker than their attackers. As said, never the easiest to save shots that don't look like they are going in. Pushes it over, they score from the corner, I'm sure people would have said something about that too?
The second is a gamble and if you see it, he actually gets a hand to it.
You didn't mention the outstanding save at 0-0....I guess that doesn't count?
