Marc Guiu

On the night of 22 October 2025, in a remarkable turn for both player and club, Marc Guiu etched his name into the history books of Chelsea FC and the UEFA Champions League.
In the fixture against AFC Ajax at Stamford Bridge, Guiu scored the opening goal—thereby becoming the club’s youngest ever goal-scorer in the Champions League, before his record was swiftly surpassed minutes later. (beIN SPORTS)
The milestone moment
Guiu, aged 19 years and 291 days, opened the scoring for Chelsea shortly after Ajax were reduced to 10 men following a red card to their captain. (Outlook India)
His goal was carved out from close range, side-footing home from a cross by Wesley Fofana soon after the numerical advantage emerged. (Outlook India)
By doing so, he overtook the previous youngest-scorer mark held by Reece James (who had scored at 19 years and 332 days) in Champions League play for Chelsea. (beIN SPORTS)
However, the twist came just minutes later: at half-time, 18-year-old Estêvão Willian converted a penalty and thus became Chelsea’s youngest ever Champions League scorer, pushing Guiu to second in the club’s record books. (ESPN)
Why it matters
-
Youth emphasis showing: Chelsea’s starting lineup that night had an average age of 22 years and some months—one of the youngest ever for an English club in the Champions League. (Outlook India)
-
Record-setting context: Not only did Guiu set (for a brief time) a record, but the match also saw three different teenagers (Guiu, Estêvão, and Tyrique George) score for Chelsea in a Champions League match—the first time in the competition’s history a club had three teenage scorers in a single game.

Career springboard: For Guiu personally, this moment marks a tangible reward for his development and invites speculation on his role in Chelsea’s future.

Making a mark in Europe’s top club competition at such a young age is a notable milestone.
The broader match context
The match itself was far from ordinary. Ajax were reduced to ten men early on (17th minute) due to a red card, which opened the door for Chelsea to press home their advantage. (Outlook India)
Chelsea capitalised quickly: after Guiu’s opener, they built a 4-1 half-time lead thanks to a long-range deflected goal by Moisés Caicedo and two penalties – one for each side – before the teenager Tyrique George made it five soon after half-time. (Premier League)
It was a night of emphatic dominance by Chelsea’s young core.
What this says about Guiu’s future
Guiu’s goal represents more than just a record: it’s a signal of trust from the coaching staff and the club environment that he can contribute at the highest level.
With Chelsea clearly willing to field and rely on younger players, his moment could herald increased playing time and responsibility.
That said, while the milestone is impressive, consistency, physical development and tactical maturity will remain key for him to establish himself.
Final thoughts
Marc Guiu’s strike against Ajax will be remembered as a record-breaking moment, even if only briefly.
While the record was overtaken almost immediately, the fact remains: he became Chelsea’s youngest ever Champions League scorer on that night.
In the context of a youthful Chelsea side rewriting history and forging a new identity, Guiu’s contribution stands out. How he builds on it will be interesting to watch.
