Don't be too disappointed. Chelsea overpaid by a lot and he wouldn't crack the top 5 for Liverpool with Mane, Salah, Fimino, Shaq, and Sturridge. I'm not sure that Pulisic will get that much playing time at Chelsea in the first 2 to 3 years of his contract unless Hazard makes the move to Spain or Italy.
It is a plus for the USMNT but unless the head coach moves away from favoring MLS players they will continue to struggle.
