Duff tempted Juanfran for the first before being brought down and Hierro tried to lift Niall Quinn's jersey up off his head for the second.
The penalties were taken by two of my players at Leeds, Ian Harte and Robbie Keane.
I was surprised to see Harte try to slot his kick to the right of the keeper and maybe that was why it was saved.
Normally he sweeps them into the other side.
Kevin Kilbane did the right thing, making sure he was there first to the rebound, but he should have side-footed the ball rather than going for power.
I was sure Keane would score the second penalty, even though it was in the final minute and was so crucial.
The bigger the occasion, the better he is.
And you could see how delighted Harte was because he and Keane are big friends.
Ireland can go out of the World Cup with their heads held high, because they've not been beaten.
I just hope there's not a big fuss about the players who missed penalties.
The fuss should be about the way Ireland have played in the competition.
The first half against Cameroon was not great, but since then they've been absolutely brilliant.
They ended up with four forwards in this match because they were so desperate to win the game.
I think the early goal Ireland conceded was a sucker punch.
It was very well-taken by Morientes but it was awful defending.
