There will be no hiding place for England manager Roy Hodgson - or his players - if the national side fail to qualify for next year's World Cup finals in Brazil from a section that on paper is weak.
Nearest Group H rivals Montenegro (26), Ukraine (27) and Poland (65) are well below 17th-ranked England in the FIFA standings.
England are strong favourites to overcome Montenegro at Wembley on Friday night, but they have yet to pick up full points against the Balkan state in their three previous competitive meetings, all of which have ended in draws.
A win against the visitors would leave Hodgson's side on the cusp of the finals, needing a win against Poland on Tuesday to confirm their spot in South America. You can study all the permutations here:What do England need to do to reach the World Cup finals?
Defeat does not bear thinking about when you study the above video.
England would have to live with the humiliation of losing out to a country that is smaller than Sheffield.
Rather than dig out his passport for Brazil, Hodgson would be picking up his P45.
Here are the main differences between England and Montenegro, a football side that only came into existence after spitting from Serbia in 2007.
Forget some of England's lame performances during recent major tournaments. Failure to escape from this group in first place would be about as bad as it gets.
