I guess you underestimate Morata and Mandzukic immensely, both of them have led their teams to CL finals. And also Dybala of course, the kid has 60 official minutes under his belt in a Juve jersey for God's sake in which he already bagged a goal... Time is of the essence with this young core and only time will provide us with the answer.
We're not exactly missing a superstar, we have superstars in every line. Yet what we are missing, is the link-up guy and hopefully we'll solve that. I agree on the Draxler part however because he doesn't seem like the ideal '10'.
