Gaich is a clumsy so and so. His finishing skills and technique are pretty poor among recent Argentine u20 strikers. Colidio was left out for him which beggars belief. Missed a sitter against Korea as well. Roffo is third choice at Boca.Good shot stopper, very decent on the ball but his decision making is all over the place. Alvarez is pretty average too. Barco needs to develop a brain but has great technical ability. Most of Argentina's best players were not picked by Batista. That includes Garay and Balerdi at the back, Garre in midfield and Almada while he does not trust de la Vega. Perez is the pick of this team. Exudes class and leadership at centre back.
