That ultimately ended in disappointment for Pulisic and his team-mates as they were beaten 1-0 by Mexico in the final.

But rather than dwell on it, the 20-year-old has moved quickly on, forgoing a long break and joining up with Frank Lampard's men, and his dedication has already impressed his new coach.

'He has had short break but fair play, he wanted to get there quickly which I appreciate,' Lampard said earlier in the week.

'It is how I would have been [coming back from holiday early]. It is a huge move for him to a big club and he is a top young player who will only go one way.

'It was important we start the season as well as we can. I know we have injuries but we will need him. I have not met him, I have spoken to him, but it is a good impression.'

Chelsea face Barcelona on Tuesday 23 June at the Saitama Stadium.
