In particular, it was a moment in the game against Spain. Ian Harte missed a penalty, was substituted and looked desperate on the bench.
Then Robbie Keane scored from the spot, and the jubilation on the Ireland bench summed up what the Irish were all about. It was a great moment.
The anger and the fury of the coaches provided the most memorable moments for me.
Giovanni Trapattoni of Italy, in particular, summed it up as yet another decision went against his side.
His frustration as he banged the dug-out and kicked a water bottle showed the true passion which the World Cup arouses.
England v Argentina was a very special game, and not just for David Beckham.
Before kick-off, the sound man on our camera crew received a phone call from his wife to say she had just gone into labour on the other side of the world!
Shortly after the final whistle he was told he had become the father of a baby girl.
I was in South Korea for their opening game against Poland and it was incredible.
We were surrounded by thousands of fans, singing and cheering hours before kick off - and the party carried on many hours after South Korea's win.
The sheer emotion and passion demonstrated by the fans was quite remarkable.
