USA coach Gregg Berhalter insists Christian Pulisic will embrace the challenge of proving himself to new Chelsea manager Graham Potter.
Pulisic is finding himself on the periphery at Chelsea.
"He's a goalscorer. He's a winner," Berhalter says.
"What I've seen from him in the last couple of years is his mentality has completely shifted, and he embraces stuff like this.
"He's not scared of challenges like this. And I'm excited to see how he performs this year."
