WATCH: Cavan Sullivan gives inside look at Manchester City training during Philadelphia Union return

Philadelphia Union's 15-year-old midfielder Cavan Sullivan shared an extensive highlights compilation on his TikTok account after returning from his two-week training stint with Manchester City in England. The nostalgia-tinged video juxtaposes Sullivan's experiences at City's state-of-the-art Etihad Campus facilities with footage from his development at Philadelphia Union's academy.

Sullivan's social media tribute to both clubs highlights the unique position of the American teenager who represents both the present and future of two distinct soccer ecosystems. The midfielder signed MLS's largest-ever homegrown contract with the Philadelphia Union in 2024.

Sullivan rejoins Philadelphia Union for their upcoming MLS fixtures, with the club set to face New York Red Bulls next in the U.S. Open Cup quarterfinal on Aug. 13.
