Chelsea ace Christian Pulisic could miss the start to next season due to his hopes of playing for the USA at the Tokyo Olympics.
The Tokyo football tournament gets underway on July 21, with the final taking place on August 7.
If selected, Pulisic would miss a crucial chunk of pre-season, with August 7 also set to be the Premier League's opening day.
The Olympic football tournament is predominantly limited to players under 23.
But at 22, Pulisic would still qualify.
The winger told NBC: "The Olympics is of course a massive honour to play in and to represent your country in an Olympics would be amazing.
"I am fully supporting the guys in qualifying now. It is something I've thought about and that I've wanted to play in.
"Obviously I can't control exactly what goes on and what is best for me at the time and the team at the time, I can't say.
"But it is something that I would like to play in."
