Consistent defender who is seen as an important squad member by coach Ricardo La Volpe. Castro, 26, has been a virtual ever present for America during the past few seasons and helped his unfancied club side win the league championship twice in the last four years. The versatile defensive player came through the ranks at America and has gone on to become one of their most valuable players. Not someone perhaps regarded as a first choice for Mexico yet, but he is an important part of the 23-man squad nonetheless.
