The drama has started even before the official kickoff of the tournament. If Ecuador is disqualified, then who will replace them? Peru, Chile or Colombia? There is some confusion related to this. Peru is the team that finished at the 5th place (and they lost the playoff to Australia). Colombia is in 6th and Chile is in 7th position.
To understand better:
Peru finished in 4th place, but if Ecuador loses the spot, it will lose the points to another teams, 8 matches to be precise.
The new chart will put Chile in 4 th place, so the spot would be to Chile, not Peru.
I believe that, unfortunately, Ecuador should be eliminated from the World Cup.
To be honest, I think FIFA will punish the player Byron Castillo, he will pay some fines, be out of a lot of matches, but FIFA will keep Ecuador on World Cup.
If Fifa decides to punish Ecuador, Peru and another teams will probably see a chance to fight to the spot and will be more complicated.
