Chelsea boss Potter says Pulisic must be ready to seize opportunity
Pulisic has made just two Premier League starts this season and has had limited playing time recently.
The American is expected to feature in the United States squad for the November 20th-December 18th World Cup in Qatar, where they have been drawn in Group B with England, Iran and Wales.
"You can imagine my focus is on Chelsea," Potter told reporters on Tuesday. "I understand that all the players have ambition and want to play for different reasons, for their families, careers or World Cups.
"That's all fine but it's my job to select the right team for whatever game. Not saying I am right all the time, I am not but somebody has got to make the call.
"With Christian I would say he has been fantastic around the place, been really good with team mates, contributed against Wolverhampton Wanderers. He is pushing for a place, pushing for a start. Things change quickly in football and he needs to be ready."
