Northern Ireland need at least a point against Germany in their final Group C match if they are to stand any chance of qualifying for the next round of the Euros.
Following their shock 2-0 victory against Ukraine in their last fixture, Norn Iron are just a single point behind Poland and Germany and would have a decent chance of going through to the round of 16 as a top third-place qualifier if they can salvage a point at Parc des Princes on Tuesday.
O'Neill's policy of containment in their 1-0 loss to Poland was widely-criticised as pundits and fans believed that his outfit were being too cautious, but that same policy may be the key for the green-and-white army when they face the Germans.
The world champions began their Euro 2016 campaign with a dominating 2-0 victory against Ukraine, but faltered in their 0-0 draw with Poland, which highlighted, amongst other things, the apparent attacking flaws in the Joachim Low's side.
Despite this, Low, who has been in charge of Germany for 10 years predicted that his side will advance to the next stage of the competition as winners of Group C.
"We want to win, we will win and we will top the group. I think we will then play in Lille for our round of 16. I don't know any other way," he told reporters.
Northern Ireland striker Kyle Lafferty was dropped for the side's historic win over the Ukraine and insists he will have no complaints is left out again against Germany.
"I don't think any of the lads who started deserve to be dropped. They sweated blood out there and they deserve another chance. The front three – Conor, Jamie Ward and Stuart Dallas – were absolutely brilliant," he said.
Both sides are expected to head into the fixture with unchanged starting line-ups with no injury or suspension concerns.
