The 20-year-old, who has been capped 22 times by the USWNT, has signed a contract with the Blues until 2030.  

Thompson said: ‘Chelsea is such an amazing club, one of the best in the world. Being able to play with players that are the best in the world is an amazing opportunity at such a young age and I want to learn, grow and develop a lot. I feel like Chelsea is such an amazing environment to do that in.’ 

Paul Green, head of women’s football at Chelsea said: 'We’re delighted to bring Alyssa to the club. She’s a dynamic winger with electric pace, who can play on either wing and is very good in one-on-one situations.  

'Alyssa is one of the best and most exciting young players in the world, and we’re looking forward to seeing how she develops further during her time with Chelsea.' 

The talented forward joined Los Angeles-based Angel City from Total Futbol Academy, a boys’ club in MLS Next, the academy system for Major League Soccer.  

Thompson became the youngest player ever to be drafted into the NWSL when she signed with Angel City in 2023. She was the number one draft pick and the first player to enter the league straight from high school.  

At Harvard-Westlake School, Thompson was named Gatorade National Player of the Year as a sophomore after recording 48 goals and 14 assists in 17 games. 

Her first senior international appearance came in October 2022, before she had been drafted. At a sold-out Wembley Stadium, Thompson replaced Megan Rapinoe in the 84th minute of the match. 

At the age of 17 years and 334 days, she became the youngest player to make her debut for the USA since Mallory Pugh in January 2016. 

In April 2023, she made her first start and played the full 90 minutes against the Republic of Ireland, becoming the first teenager to start a match for the USWNT since 2018. 

She has since become a regular in the USWNT set-up, with 22 caps won and three goals scored. Thompson departs Angel City having netted 15 times in 63 appearances.  

Everyone warmly welcomes Alyssa to the club, and we wish her every success during her time as a Blue!
