In Full support of Trap.
Depends on whether we're seeded or not, we can beat Bosnia, but anyone else and we'll get beaten to a pulp.
You can beat more teams (2nd placed teams), not just Bosnia, but I can also imagine you being beaten by them, including Bosnia (ex-Yu teams have been a tough nut for your NT, traditionally, and Bosnia has a pretty good team, better than some other 2nd placed teams at the moment, like Slovenia, for example) .
Anyway, as you said, lots depends on the seedings and the teams will be seeded on the basis of the next FIFA World Ranking, which will be published on 16 October.
In this case you stand almost no chance to be seeded.
No matter who's 2nd placed in group 4 where it's between Germany and Russia, will be seeded in the draws. France from group 7 will be seeded too. If Croatia from group 6 wins the 2nd place, then they'll be seeded too. Then there is the Czech Republic from group 2, that is also better placed than Ireland, but the Czechs still need a lot of work to win the 2nd place.
At the moment these are the 2nd placed teams (Norway won't make it so i won't count them)
1. Sweden
2. Greece
3. Slovenia
4. Russia
5. Bosnia
6. Croatia
7. France
8. Rep. of Ireland.
Current FIFA rankings:
6. Russia (Germany is 4th)
9. Croatia (Ukraine is 25th)
10. France
12. Greece (Switzerland is 15th , Latvia 58th, Israel is 22nd)
38. Republic of Ireland
41. Sweden (Denmark is 16th, Portugal 17th)
46. Bosnia and Herzegovina
54. Slovenia (Czech Republic 18th, Poland 36th, Northern Ireland 31st)
------------
If you look into it, you'll see that your team's only chance to be seeded is Sweden to win the 2nd place in group 1, Slovenia to win the 2nd place in group 3 and Latvia to win the 2nd place in group 2.
That's almost impossible.
If things stay as they are then one of Russia, France, Croatia and Greece will be Ireland's opponent in the play-offs. I believe that you stand great chances against Greece, it's 50-50 against Croatia and you also stand solid chances against Russia.
Against France it will be tougher.
