Chelsea boss Frank Lampard is delighted with the attitude of Christian Pulisic.
Lampard revealed the USA forward refused to take a proper holiday in a bid to hit the ground running.
He will link up with his new team-mates in Japan on Tuesday, just nine days after playing in the Concacaf Gold Cup final - won by Mexico.
After their friendly win over St Patrick's Athletic, Lampard said: Christian is flying in separately to join us as he has had a short break
"But, fair play, he wanted to get there quickly which I appreciate. It is how I would have been.
We have injuries and we will need him.
I have not met him, I have spoken to him, but it is a good impression."
