USMNT prospect Cavan Sullivan scores goal for Manchester City U21s while undergoing summer training camp with English club

American forward Cavan Sullivan, 15, scored for Manchester City's U21 team in a 3-2 loss to Buxton of the National League North on Saturday, making his first mark on the club that he will join permanently upon turning 18.

Sullivan, who signed the largest Homegrown Deal in MLS history in 2024, had a clause inserted in the contract that upon turning of age, he would join the Premier League giants on a permanent deal from the Philadelphia Union.

This July, Sullivan is participating in a training camp with the English club, and he made his first appearance on Saturday off the bench. Sixteen minutes into his cameo, he found the back of the net for their first goal of the day in the second half in the 61st minute.

Sullivan is widely regarded as one of the most talented players in his age group across the world. He recently earned his first start in MLS for the Union, and has recorded two other senior starts this campaign in the Lamar Hunt U.S. Open Cup for Philly.

In total, he's made eight appearances for the senior team this season, while at the MLS NEXT Pro level, he has nine appearances this season, scoring five goals and recording one assist.

Sullivan was named to GOAL's top-50 NXGN wonderkids in world football in 2025.

The teenager will miss the Union's match against the Colorado Rapids Saturday evening, but will return to the club next week.
