Goals and assist does not say all the things. Most attackers fail in stamford bridge. See Lukaku. Only Costa and Dogba has succeeded. Pulisic has played out of position multiple times and also did not start all match till Late December and january. While he has dropped a 7.5/10 performance every game he has played in LW. I don't know how you are saying he is not good even after watching all matches. Even in that Carabao cup final, except that one chance eh missed, he was good.
