Colidio has joined Tigre on-loan.
Martinez told FCInterNews: "We signed him because he is a young striker with a bright future ahead of him.
“He can adapt to various positions in attack.
“And we've known about him from an early age, from his training with Boca," he continued, “he's a great young man boy and an exemplary professional."
“He's going through a logical process and remains very young today.
“For me, what he has already experienced in Europe will help him to mature as a footballer," he added. “And you'll see that he'll grow even more this year."
