The brutally cruel defeat left Northern Ireland needing an unlikely maximum haul from games next month at home to the Dutch and away to Germany to get out of Group C.

"When the draw was made in Dublin we knew we were in the toughest group," O'Neill said.

"We knew Germany were the pot two team everyone was trying to avoid but we were allocated that group and we had to meet that challenge head on.

"What we have to do is try to win the game in Belfast and then go into the game in Frankfurt with something to play for.

"We can only do that if we beat Holland. Given the nature of how we lost here it would be nice to beat Holland in Belfast if we can."

O'Neill's side had executed his game plan well on the night, aware of their technical deficiencies compared to the Dutch but prepared to make up for it with dogged pressing, harassing Holland into mistakes and knocking them off their stride.

O'Neill spoke before the match of sowing doubt in the minds of a young Dutch team looking to avoid the ignominy of failing to reach a third successive major tournament, and for 80 minutes it appeared to be working.

"Maybe we're not a team that can compete technically but we can compete in terms of structure, spirit and heart and that's what we did," O'Neill said.

"But ultimately I don't tend to look back on games that we've lost with any great pride and this game will be no different."

Given the uphill task of getting out of Group C, Northern Ireland's best hope will be to secure a place in the play-offs next March. Results on Thursday strengthened their chances, though it is still not guaranteed.

In the short term, attention turns to Monday's friendly against the Czech Republic in Prague.

O'Neill will use the game to rest a number of regulars and focus on giving experience to the fringe players in his squad who sorely need it.

"We have to give opportunities to some of the players," he said. "Obviously a friendly off the back of a game like this is not that significant but equally we have to get game time into the young players.

"The players on the periphery of the square are playing their club football at a pretty low level and this is the top level. The Czech Republic will provide a stiff test for us too and hopefully it's a game we can pick ourselves up for."
