Michael O'Neill has described Ronald Koeman's criticism of Northern Ireland as "irrelevant to me".
The Netherlands boss labelled Northern Ireland's approach to Thursday night's Euro 2020 qualifier as "outrageous" and "terrible to watch".
The Dutch scored two injury-time goals as they came from behind to beat Northern Ireland 3-1 in Rotterdam.
"It's irrelevant to me," said O'Neill ahead of NI's friendly with the Czech Republic on Monday.
"You give respect to the opponent and how they play. We didn't go there to entertain Ronald Koeman, that wasn't the purpose of what we did."
He added: "If you're picking players from Barcelona, Juventus and Liverpool you can play a certain way. If we were so terrible, why were we so difficult to beat? And clearly we were extremely difficult to beat.
"It's disappointing that a manager of that class feels the need to say that. It's not something we need to dwell on."
