Christian Pulisic is prepared to cut his summer break short in order to make an instant impact at new club Chelsea and on their expected new manager, Frank Lampard.

Chelsea agreed a £57.6m deal to buy Pulisic from Borussia Dortmund in January, but allowed him to spend the rest of the season on loan at the Bundesliga club before joining up with the squad.

The 20-year-old’s arrival is in danger of being delayed though because he is currently away with USA competing in the Concacaf Gold Cup.

USA are one of the favourites to win the competition and the final takes place on July 7, three days after the first batch of Chelsea’s senior and youth players – those not involved in internationals this month - report for pre-season training.

Chelsea have a policy of allowing talent involved in summer international fixtures to have extended time off to compensate.

But Standard Sport understands that Pulisic is considering not taking much of a vacation at all, even if the USA go on to lift the Gold Cup.

Chelsea depart for a pre-season tour in Japan just over a week after the showpiece occasion and the attacking midfielder is looking to be on the trip.

With Lampard expected to be confirmed as the club’s new coach soon, Pulisic doesn’t want to be playing catch up with the rest of his team-mates and is ready to postpone a proper break until the following year.

Pulisic is under pressure to impress as he is likely to be the only new face in the squad due to the club's two-window transfer ban, which has been appealed to the Court of Arbitration for Sport, and the departure of Eden Hazard to Real Madrid.
