every defender is prone to mistakes, show me one that isn't? Mori makes them maybe more than some but hes a very good player, hes also first choice centre back for one of the top 3 international teams in the world, I think that qualifies him as good enough for our team too personally.
Our form has improved a lot since he made the starting 11, he also chips in with more goals than the average CB
Argentina are in major trouble defensively as Otamendi, Funes Mori and Mascherano seriously lack pace.
Even Venezuela's attack ripped them to pieces. Peru and Ecuador too.
Iirc I saw the donkey Dimichelis playing a few months ago.
Being a first choice centre half for Argentina ain't the currency it used to be.
