He has promising talent but seemed to have been rushed to the first team.Whoa whoa whoa...... Calle was the epitome of a Homeless Journeyman in that he was constantly loaned out by his home club for 4 straight years to 3 different teams - that's 4 years with only 26 appearances. His home team knew he wasn't any good and his temporary teams figured it out too.
In less than half that time, Bravo has gotten 34 games with his home club Boca, which is one of the absolute best teams in the Americas and produces talent like few others.
I'm guessing Vieira sees him as a prospect he can likely get the most out of now that he's a bit older.
