England go into their clash with Poland with qualification in their own hands, and we look at all the potential permutations for Roy Hodgson's side.
So, if all goes plan, then England win at Wembley and that is it, they have won the group and are through to Brazil.
It is if England don't win that things get a bit more interesting.
Ukraine face San Marino and few people would expect nothing less than three points, which means that, if England draw or lose to Poland, they would not top the group.
England already know, however, that if they do finish second they are guaranteed a play-off spot, But, because there are nine groups in Europe, one team who finishes second will miss out.
The team to miss out will be decided after all the games have been played on Tuesday. For those groups containing six teams - which is all of them apart from Group I - the results against the bottom placed team will be removed before working out who has the best records.
Group A: Belgium have won the group, whilst Croatia are confirmed in second and a point against Scotland would guarantee a play-off spot.
Group B: This group appears favourites to miss out on a play-off spot with Italy having secured top spot. Bulgaria, Denmark, Czech Republic and Armenia can all finish second but realistically the only team with a chance of a play-off spot would be Armenia, but they face the daunting task of needing to win in Italy to have any hope.
Group C: Germany have won and Sweden have a play-off spot confirmed.
Group D: Holland have top spot tied up, but Turkey, Romania and Hungary are battling for a play-off spot. If Turkey beat Holland at home, they will have second spot, But, if not, then Romania will take it with victory over Estonia. If they slip-up then Hungary can win. If all three lose then the possibility is there that this group could miss out on a play-off spot.
Group E: Switzerland have secured the group - second place and a play-off spot is Iceland's if they match or better Slovenia's result.
Group F: The top spot is virtually Russia's. For Portugal to catch them they would need to hope Fabio Capello's side lose in Azerbaijan and then over-turn a seven-goal deficit.
Group G: Another group coming down to the wire with Bosnia and Greece level on points going into the last set of games. Greece face winless Liechtenstein, so Bosnia know only a win will be enough in Lithuania, but if they do then that will see them through as their goal difference is far superior.
Group H: England, see above
Group I: Defending champions Spain are just about through. For France to take top spot, they would need a big win over Finland and then hope Georgia win in Spain.
The European play-offs will be played in November.
Around the world
Around the world and all the sections are edging towards their final stages...
In Africa, they are down to five play-off matches, the winners of each will make it to Brazil.
In Asia, Iran, South Korea, Japan and Australia are already qualified whilst Jordan beat Uzbekistan in the play-off, and they will now take on the fifth placed team from South America - likely to be Uruguay.
In South America, hosts Brazil, Argentina and Colombia are already through, and Chile and Ecuador just need to draw against each other in their final match to keep Uruguay in fifth.
In Concacaf, USA and Costa Rica have already finalised their places at the World Cup finals with Honduras set to join them as they need just a point from their trip to bottom placed Jamaica. The fourth place team will then play-off against Oceania winners New Zealand for the final World Cup spot and that is set to be Mexico.
