Robin van Persie and Ibrahim Afellay both netted braces as the Netherlands thrashed Northern Ireland in Amsterdam.
The hosts dominated the match from start to finish, enjoying over 70 percent of possession and denying their British opponents a single shot on target.
Van Persie opened the scoring after 11 minutes with a header, before Wesley Sneijder doubled the lead four minutes later with a low free kick.
Bert van Marwijk's team were four goals ahead by half time as Van Persie converted a penalty before setting Afellay up for his first of the evening.
The Arsenal forward assisted Afellay again six minutes into the second half, before Ron Vlaar headed in Afellay's corner to complete the rout with eight minutes remaining.
Holland begin their Euro 2012 campaign on June 9 against Denmark.
