USA legend Clint Dempsey has claimed that Chelsea star Christian Pulisic must seize the chance to showcase his talent at the World Cup ahead of the January transfer window.

The winger has struggled for minutes at Chelsea this season under both Thomas Tuchel and Graham Potter.

“All eyes on Christian,” Dempsey insisted on Fox’s World Cup coverage ahead of the US’s first game against Wales.

“You’ve got to prove why you should be on the field. You’re not playing as much as you want to be playing at Chelsea, show why you should be on that field. The January transfer window is coming up.”

Former US goalkeeper Kasey Keller told Pulisic earlier this month he should consider taking a paycut and leaving Chelsea to progress his career.

“I think part of the issue for Christian Pulisic initially was injuries. It’s been two steps forward, two back,” Keller said.

“He’d really establish himself, and then he’d get injured. I never have a problem with a player looking for more playing time.

“I understand there is potentially less salary out there than Chelsea, but there’s also a part of you that says you have a finite amount of time.”

Keller added: “What I’d love to see Pulisic do is win a starting spot at Chelsea, honestly that’s what I’d love more than anything but there is a point where he needs to decide what’s more important.”
