Ecuador 1-1 Argentina
A Sergio Aguero penalty in the first minute gives Argentina the early lead after Dominguez brought down Palacios in the box.
Segundo Castillo equalised for the hosts with a superb header from a whipped free-kick into the six-yard box.
A moment of madness in the dying moments of the game from Javier Mascherano saw him given a red card after lashing out at a medic.
