Cavan Sullivan arrives at Sports Illustrated Stadium with momentum behind him and a point to prove on the road. The 17-year-old has been central to Philadelphia Union’s upturn in form under interim manager Ryan Richter, contributing goals and assists across Leagues Cup and MLS play over the past few weeks. The Union beat New York City FC 3-2 away just two weeks ago, and Sullivan was a driving force in that comeback. Now he faces a Red Bulls side that has won just once in their last five, making this an opportunity for the youngster to underline his standing as one of the more exciting teenagers in MLS.

Cavan Sullivan’s recent form
Sullivan has been the standout name in the Union’s recent resurgence. He was named to the MLS Team of the Matchday bench for his performances, recorded contributions in Leagues Cup matches against Necaxa and Santos Laguna, and delivered a standout display in Philadelphia’s 3-2 win at New York City FC on August 16. That result was the kind of performance that shifts perception, and Sullivan’s role in the comeback earned him widespread recognition.
Under Richter, the Union have gone W-W-D-D in their last four across all competitions after a difficult stretch. Sullivan fits naturally into the structure Richter has implemented, using his ability to drive at defenders and combine in tight spaces. Philadelphia’s attack has averaged over two goals in their last three matches where Sullivan has been prominent, a signal that the team’s creativity runs through him.
The tactical matchup
New York’s defensive record tells a difficult story: the Red Bulls have conceded 43 goals in 21 matches this season, the second worst in the Eastern Conference. That figure gives Sullivan a real platform. Red Bulls defenders D. Nealis and J. Mina will likely be tasked with tracking his runs, but the numbers suggest New York’s backline has been vulnerable to direct, vertical play throughout the campaign.
Michael Bradley’s side has shipped goals in each of their last five league matches, going D-L-L-W-L in that stretch. Philadelphia will target the space behind New York’s wide defenders, and Sullivan’s ability to arrive late into the box or drift into pockets between the lines makes him a consistent threat against a defense that has been leaking.
What’s at stake for him
Philadelphia sit 13th in the Eastern Conference with 21 points, five points outside the playoff positions with a run of form that has given them legitimate reason to push up the table. Sullivan is not just a feel-good story at this point. He is a player whose performances are directly shaping the Union’s trajectory. A strong showing at Sports Illustrated Stadium, where Philadelphia have historically done well against New York (seven wins in the last ten head-to-head meetings), would cement his status as the team’s central figure heading into the final stretch of the regular season.
The h2h record is telling: Philadelphia won 3-1 in this exact fixture back on July 22, with New York recording just one win in the last ten meetings. Sullivan was not necessarily the star of that July match, but he has grown since. This visit to Red Bull Arena is a chance to show that his form is not a flash, but a consistent level.

Our Prediction
Philadelphia have enough momentum and a favorable defensive matchup to collect at least a point here. If Sullivan is given space to operate between the lines, which New York’s backline has consistently allowed this season, he could be the difference. Expect the Union to score, and Sullivan to be involved directly or indirectly. A Union win on the road would be a genuine statement of intent from Richter’s side.
