It is a bit early to say if he assists or scores enough or not. I get that he has not done that at Boca neither, but he is young and has been developing his game different areas. From what we HAVE seen, he has shown drive, intelligence, passing and creation skills, physicality and ball-winning capabilities. Many of those things we saw from Vidal and Pogba (although not near them (yet)). When he has played (although a very small sample), he has been the dude from midfield connecting defence and attack the best and I wouldnt be surprised to see him start getting assists and goals on this team!
