#1. The possibility of Lionel Messi missing the World Cup still exists
In the end, though, it will still always be about Lionel Andres Messi, won't it?
Brazil eased past Ecuador to finish winners of the group - an incredible performance (overall) from Tite's men - while Chile failed to get past Paraguay and lost 2-0 to the "minnows". This was good news for La Albiceleste as they come closer to Chile and have a real chance of working their way back up the rankings to an automatic qualifying position. But it also brought Paraguay closer to Argentina - such is the tight nature of qualifying on this continent!
A World Cup without Messi would be a disaster - some convoluted conspiracy theories suggest this may be a reason behind FIFA's relaxation of the four game ban they'd earlier imposed on the Argentine captain - but we might have to wait till the final round of qualification to get a confirmation on the great man's participation in Russia 2018.
Here's how the table looks like after a frenetic day's action in South America (read as rank, nation, points accrued - all teams apart from Peru and Bolivia have played 15 games as of the time of publishing)
1. Brazil - 36
2. Colombia - 25
3. Uruguay - 24
4. Chile - 23
TOP 4 AUTOMATICALLY QUALIFY
5. Argentina - 23
FIFTH PLACE GOES INTO PLAY-OFF WITH OCEANIA (i.e. New Zealand
6. Paraguay - 21
7. Ecuador - 20
8. Peru - 18
9. Bolivia - 10
10. Venezuela - 7
