Chelsea fans are just like anyone else. They have their biases and prejudices. If he performs well he will be accepted and possibly loved. They may consider him an excepption. If he doesn't do well, than they will give him a hard time and look for a reason that he was signed. What Pulisic has going for him is a reasonably good start to his career....I would say excellent but his transfer fee puts him in the stratosphere with the very top players. He is no longer a mortal but a soccer god and there has never been an American in his position (like there was never a PL coach before Bradley. He will need to be successful from the start because he won't get a long leash.
