Van Marwijk: Score irrelevant
Bert van Marwijk refused to get excited after seeing his side hit Northern Ireland for six in their last warm-up game before Euro 2012.
Robin van Persie and Ibrahim Afellay scored twice, whilst Wesley Sneijder and Ron Vlaar also netted as the Dutch signed off in style in Amsterdam.
But the Holland coach refused to join the Oranje's party atmosphere.
He said: "I'm satisfied with the execution of our tactical plan today but the score means little to me as they were very poor opponents."
Van Marwijk preferred instead to point to a possible weakness in his squad.
He continued: "My main concern is at left-back because Giovanni van Bronckhorst is now retired and his successor Erik Pieters is injured."
Jetro Willems took the position against Northern Ireland but the boss does not know if he is ready.
Van Marwijk said: "Willems is young and has a lot to learn and Stijn Schaars has to get used to this position.
"Wilfred Bouma is another option."
