Keep in mind that Ecuador has already 4 points more than the 5th and there are only 2 games left.
He would only drop to fifth if he loses both games and Peru wins every game. But the game against Uruguay will not be easy.
Brazil and Argentina both playing against much weaker opponents as well which means that there is a good chance we could end up seeing the top 4 winning their games and not having any sort of problem at all. Not really that shocking to see to be fair.
