Atlanta United Early career Wiley grew up in Atlanta's Morningside neighborhood, playing soccer, football, basketball, and baseball in elementary school before focusing on soccer as he grew older. At 11 years old, Wiley participated in an open tryout for enrollment in Atlanta United's youth academy, and secured one of 30 spots on the fledgling club's U-12 team. Joining the academy just before the professional outfit began their inaugural
Major League Soccer season, Wiley remained heavily involved with the club through his debut with
Atlanta United 2 in 2020. In 2018, Wiley served as a ball boy as Atlanta defeated the
Portland Timbers in the
2018 MLS Cup final. In July 2020, Wiley made his professional debut with Atlanta's
USL Championship affiliate, appearing in a 2–1 defeat to the
Tampa Bay Rowdies.
Professional On January 18, 2022, Wiley signed a
homegrown player contract with
Atlanta United. In February, he made his MLS debut against
Sporting Kansas City, scoring late in Atlanta's 3–1 victory. With the team suffering from a number of injuries, Wiley found himself moving up the depth chart, finishing the 2022 season with 26 league appearances to his name. In February 2023, Wiley was named amongst American Soccer Now's top 20 young Americans to watch during the
2023 Major League Soccer season. It didn't take Wiley long to live up to those expectations, scoring twice and providing an additional assist in Atlanta's week three victory over
Charlotte FC. At 18 years and 79 days of age, he became the fifth-youngest player in league history to contribute to three goals in a single game. As a result of that performance, he was named to the league's Team of the Matchday for week three and was named Player of the Week. He added his third goal of the season the following week in a 5–1 victory over Portland. Wiley concluded the season with four goals in 33 MLS appearances, as Atlanta were eliminated from the playoffs by eventual champions
Columbus. Wiley was believed to have a high upside, but remained "an incomplete attacking player" as well as "a flawed defensive one" according to analysts from
The Athletic, owing to lapses in his defensive decision-making and awareness.
Chelsea On July 22, 2024,
Premier League club
Chelsea announced the signing of Wiley on a six-year contract, paying a transfer fee of approximately £8.5 million.
Loan to Strasbourg On August 11, 2024, Wiley was loaned out to

Ligue 1 club
Strasbourg on a season-long deal. He made his competitive debut on August 18, 2024, in Strasbourg's 1–1 draw with
Montpellier.
Loan to Watford On February 3, 2025, Wiley was recalled from his loan at Strasbourg and joined
EFL Championship club
Watford on loan. On July 22, 2025, Watford extended his loan for one more season. However, the loan was terminated on January 9, 2026. ==International career==
