Teen Sensation Cavan Sullivan Blocks Lionel Messi's Path to MLS Glory

Cavan Sullivan's remarkable season has elevated him to the status of one of America's finest young soccer talents, and he now finds himself in the running for the 2026 MLS MVP award—a prize he could realistically claim, denying Lionel Messi an unprecedented third consecutive title.

Sullivan was just 14 when he inked the most lucrative homegrown contract in MLS history, which includes a clause sending him to Manchester City upon his 18th birthday. Two months later, he became the youngest player ever to feature in a league game across any major professional sports league in the United States and Canada.

This season, Sullivan has evolved from a promising prospect into a genuine first-team contributor, demonstrating his ability to impact MLS matches. After going without a goal or assist across his first 19 appearances for the Philadelphia Union, Sullivan launched 2026 by recording his first senior assist against Trinidad and Tobago's Defence Force in the Concacaf Champions Cup.

He surpassed that in the second leg, netting his first two senior goals and contributing two assists in a commanding 7–0 win as Philadelphia advanced to the Round of 16 with a 12–0 aggregate scoreline. Sullivan then registered his first MLS assist on Apr. 4 at Charlotte before finding the net for the first time in MLS on May 13 in Orlando—unknowingly laying the groundwork for an MVP-caliber breakout season.

Since August began, Sullivan has elevated his performances dramatically, accumulating eight goals and 10 assists across 14 MLS outings, along with a goal and an assist against Necaxa in the Leagues Cup. He has become the heartbeat of a Philadelphia Union side that has engineered one of the most unlikely turnarounds in recent MLS memory—they will now face the New England Revolution in the first round of the MLS Cup Playoffs.

Sullivan leads the Union in assists (14), goal contributions (23), and successful dribbles per 90 (2.6), cementing his place among MLS's elite. For a club that had gone from hoisting their first Supporters' Shield to flirting with the Wooden Spoon within a matter of months, his emergence could not have been more timely.

The Union sat at the foot of the standings heading into the World Cup break, but they rebounded spectacularly on the back of Sullivan's brilliant performances, ultimately finishing sixth in the Eastern Conference. In doing so, they became the first club in MLS history to reach the playoffs after collecting seven or fewer points from their opening 15 games, eclipsing the Seattle Sounders' previous benchmark of 12 points set in 2018.

Sullivan's rapid rise caught the attention of USMNT head coach Mauricio Pochettino, who handed him his international debut during the September/October window. After starting against Peru and coming on as a substitute against Chile, Sullivan made history against Mexico, becoming the youngest scorer in USMNT history with a thunderous long-range strike that doubled the Americans' lead over their fierce rivals on Texas soil.

The teenager has kept his spot in the squad for this month's Concacaf Nations League quarterfinals against Haiti, and while Pochettino appears set to leave for Manchester United, his replacement will undoubtedly be keen to build around one of American soccer's most exciting young stars.

Sullivan's value has grown so significant that his absence is felt almost as strongly as his presence. With the teenager ruled out by an ankle injury, the Union suffered a 2–1 loss at New England Revolution—their first MLS defeat in five months—before drawing at Nashville and losing to Cincinnati.

Sullivan made a powerful return to the starting lineup on Decision Day, however, scoring twice as the Union dismantled Toronto FC 4–1 to secure an automatic playoff spot. He opened the scoring and doubled Philadelphia's lead after the break, delivering a well-timed reminder of just how vital he has become to the team.

Having only turned 17 two months ago, Sullivan has firmly established himself as one of North America's premier players, and his inclusion among the finalists for the Landon Donovan MLS MVP comes as little surprise. Fellow nominees include Evander (FC Cincinnati), Guilherme (Houston Dynamo FC), Hany Mukhtar (Nashville SC), and Lionel Messi (Inter Miami CF), who is chasing an unprecedented third straight MLS MVP honor.
