Named in Ruben Amorim's youthful starting XI to face Brentford, Obi didn't just make a debut - he launched what many are already calling the dawn of United's next great attacking talent.
Surpassing Mason Greenwood's previous age record by nearly 80 days, Obi's inclusion wasn't just a token gesture. Amorim, preparing for Thursday's Europa League clash with Athletic Bilbao, made bold rotational choices - but made it clear this was no gamble.
"This isn't about pressure or proving anything," Amorim told Sky Sports. "Chido showed maturity against Wolves. He's earned this, and I believe he's ready for this level."
The move is part of a wider youth revolution at Old Trafford. United's starting lineup boasted an average age of just 22 years and 270 days - the third-youngest in Premier League history. For a club known for its rich tradition of developing stars, from the Class of '92 to Rashford and Garnacho, Obi represents the latest chapter.
A former Arsenal academy standout, Obi shocked many when he declined a professional deal in North London last October to sign with United. The decision raised eyebrows, but his performances have already justified it. From his jaw-dropping 10-goal performance against Liverpool at youth level to scoring 32 goals in 18 U18 matches, Obi's youth career reads like a prodigy's script.
Though he's yet to feature in United's Europa League campaign - deemed not first-team ready when squads were submitted - his recent rise suggests he won't be overlooked for long. With five Premier League cameos and a standout FA Cup performance under his belt, Obi is rapidly turning promise into production.
While the football world watches his development closely, one thing is clear: Chido Obi isn't just the Red Devils' youngest starter. He might just be their most exciting new project.
