He was mostly on the bench at the World Cup. He did not feature at all against France, came on in the second half against Croatia and Australia, started against Netherlands, Mexico. He definitely had a limited role and a very small one in the last two games.I can agree with your first sentence but Martinez literally won the World Cup (where he was heavily involved throughout the tournament) and the Copa America this summer gone as the undisputed starter.
Copa America yeah but I’d need to see him exposed more in big games to really have a shout at top 5.
