Not sticking your penalty straight at the keeper and one into the top tier would be a start.
Not side footing it into the arms of the keeper as if placing a back pass would have been nice.
Not slipping over as you're about to strike the ball because you're too concerned about your body shape...
Losing on pens say 6-5 and the one you missed was a world class save isn't choking, that is just bad luck. BUT I agree, the pens we missed had chokers written all over them. Scuffed shots, slips, blasts way over the bar, under hit side foots. Can't remember one of them being an outstanding save...
Those penalty misses were all choking! Can't remember one of those misses being a world class save, they were mostly dreadful choking in the back of your throat chokers chokes.
I don't think it's the same though. No matter how crap we are, teams always play us like we're a top team, never taking playing England likely. Even if we are logically an underdog, we're never treated as one.
