Greece boss Claudio Ranieri knows there is no margin for error as the Italian bids to take the 2004 European champions to France in 2016.
Greece host Group F leaders Northern Ireland at Stadio Georgios Karaiskakis in Piraeus on Tuesday.
Ranieri takes Greece into the third match of his reign after an opening loss to Romania and a draw with Finland which leaves the side up against it in a bid to make the European Championship finals.
"I know I have to arrive in the finals in Paris, that is my goal,'' the former Valencia, Chelsea and Roma boss said.
"If we do not reach Paris it is a disaster me, for everybody, and I would be the chief executive of the disaster.
"My job is hard but I love this job.''
Ranieri is taking the threat of Northern Ireland seriously, though Greece remain strongly fancied on their home turf.
Having seen a number of surprising results over the past week, Ranieri is wary of any side carrying the underdog tag.
"It is very important to beat Northern Ireland,'' he said.
"I am not surprised they are top because I know football very well and football is changing. All teams can win. Look at Spain, they lost (to Slovakia), look at Germany, they lost (to Poland), look at Russia, a draw (with Moldova).
"This is and football is fantastic. The best team does not win every time. In other sports maybe, in football, no.''
Northern Ireland have beaten Hungary and the Faroe Islands in their first two games.
Hungary travel to Torshavn to play the Faroes, seeking a first win after Saturday's draw with Romania.
Hungary captain Balazs Dzsudzsak knows the group is tight.
The Dynamo Moscow midfielder said on uefa.com: "Our group is now maybe the most balanced of them all. Four teams have equal chances of qualifying or not."
Defender Dorin Goian has been ruled out of Romania's trip to Finland after rupturing a muscle in his left leg against Hungary.
Bogdan Mitrea has been called up for the trip to Helsinki to play Mixu Paatelainen's men.
