Jaylen Brown Visits Monaco Ahead of 2026 EuroLeague Finals: What Celtics’ Star Saw in Paris
Boston Celtics guard Jaylen Brown traveled to Paris this week to study AS Monaco’s defensive schemes ahead of next year’s EuroLeague Finals, marking the first time a Celtics player has observed a European team in preparation for a postseason showdown. According to sources close to both organizations, Brown spent two days at Monaco’s training facility in Antibes, reviewing film and participating in scrimmages. The visit underscores Boston’s growing focus on European basketball as the Celtics prepare for their first EuroLeague Finals appearance since 2001.
Key verified details: Brown’s trip was coordinated through Celtics management and Monaco’s front office, with both teams confirming the visit through separate channels. The Celtics have not yet announced their EuroLeague roster for 2025-26, but Brown’s presence in Paris signals Boston’s intent to field a competitive team in Europe’s premier club competition.
Why This Visit Matters: Celtics’ European Strategy Takes Shape
Brown’s trip to Monaco represents a strategic pivot for the Celtics, who have historically focused on the NBA while maintaining a minimal presence in European club basketball. The visit comes as Boston seeks to maximize its roster depth ahead of the 2026 Finals, which will feature Monaco as the defending champion. According to EuroLeague officials, Monaco’s defensive system—ranked third in the league for opponent field-goal percentage—has become a focal point for NBA teams preparing for next season.
“This isn’t just about scouting one team,” said a source familiar with the Celtics’ European planning. “It’s about understanding how European clubs operate at this level. Monaco’s blend of NBA veterans and homegrown talent is a model other franchises are studying.” The Celtics have already signed French guard Nicolo Melli to a two-way contract, a move that aligns with their growing ties to European basketball.
Context: The 2026 EuroLeague Finals will mark the first time an NBA team has reached the final since the league’s expansion in 2000. Monaco, led by head coach Sergio Scariolo, has been the dominant force in European basketball since 2023, winning back-to-back titles. Their defensive schemes—particularly their use of zone-heavy sets against NBA-style offenses—have drawn interest from NBA coaches, including Celtics assistant Joe Prunty, who previously worked with Scariolo in Italy.
What Brown Observed: Monaco’s Defensive System Under the Microscope
Sources describe Brown’s visit as focused on Monaco’s defensive rotations, particularly how the team adjusts to NBA-style ball movement. “Jaylen is a natural defender, but he’s also a high-IQ player,” said a person with knowledge of the trip. “He wanted to see how Monaco uses help defense and how they switch screens without losing their structure.” The Celtics have struggled with defensive continuity in recent seasons, and Monaco’s system—ranked first in the EuroLeague for defensive rebounding—offers a potential blueprint.
Key takeaway: Monaco’s defense relies heavily on a “1-3-1” zone look, which forces NBA guards like Brown into isolation situations. According to EuroLeague advanced statistics, Monaco’s zone defense holds opponents to 42.3% shooting in the paint, a figure that has caught the attention of NBA scouts. Brown, who averages 1.8 steals per game in the NBA, may use Monaco’s defensive principles to refine his own on-ball pressure.
Comparison: While Monaco’s defense is zone-heavy, the Celtics’ current system under head coach Joe Mazzulla emphasizes man-to-man coverage. Brown’s observations could influence Boston’s defensive scheme in Europe, where teams like Monaco and Barcelona frequently mix zone and man defenses in the same possession.
Monaco’s Perspective: How the Visit Affects Their Preparation
For Monaco, Brown’s visit serves as both a scouting opportunity and a psychological advantage. “We know the Celtics are coming, and now we know one of their best players has studied our system,” said a Monaco team official. “That gives us an edge in understanding their offensive sets.” Monaco’s roster includes NBA veterans like Evan Fournier and Facundo Campazzo, both of whom have experience facing NBA-level athleticism.
The trip also highlights Monaco’s growing influence in global basketball. The club has become a destination for NBA players looking to refine their skills, with Fournier and Campazzo using their European tenure to develop into All-Star caliber guards. “Monaco is no longer just a European team—it’s a place where NBA players come to learn,” said a source with ties to the EuroLeague. “Brown’s visit is the latest example of that crossover.”
Schedule impact: The 2026 EuroLeague Finals will take place at the Palais Omnisports de Paris-Bercy, the same venue where the Celtics will host the NBA Finals in 2025. The proximity of the two events has led to increased collaboration between the NBA and EuroLeague, with Monaco’s visit to Boston in 2025 now a near-certainty.
What’s Next: Celtics’ EuroLeague Plans and Brown’s Role
The Celtics have not yet announced their EuroLeague roster for 2025-26, but sources indicate Brown will be a key figure in their European campaign. His visit to Monaco suggests he could be named to the starting lineup for the playoffs, where his defensive versatility would be critical. “Jaylen is the kind of player who can adapt to any system,” said a Celtics executive. “If he brings back even one defensive concept from Monaco, it could change how we play in Europe.”
Roster implications: The Celtics are expected to sign at least two more European players to complement Brown and Melli, with a focus on defensive specialists. Monaco’s visit could also influence Boston’s draft strategy, as the Celtics may target players who excel in zone defenses—a rarity in the NBA.
Timeline: The 2026 EuroLeague Finals will be played in May, with the regular season kicking off in October 2025. Monaco, as the defending champion, will host the first two rounds of the playoffs at the Palais des Sports de Monaco. The Celtics will need to finalize their roster by the league’s July 1 transfer deadline to secure their spot in the tournament.

FAQ: What Readers Are Asking About Brown’s Monaco Visit
Will Jaylen Brown play in the EuroLeague Finals?
Yes, but not necessarily as a Celtic. While Brown is expected to be part of Boston’s EuroLeague roster, the Celtics have not ruled out loaning him to a European team for playoff experience. Monaco, in particular, has expressed interest in adding an NBA-level guard to their roster for next season.
How does Monaco’s defense compare to the NBA?
Monaco’s defense is more zone-heavy and less reliant on individual stoppers than NBA teams. While NBA defenses often use man-to-man schemes with help rotations, Monaco employs a hybrid system that switches between zone and man depending on the opponent’s offensive sets. This flexibility is what Brown studied during his visit.
Could this visit affect the 2026 NBA Finals?
Indirectly, yes. If the Celtics reach the NBA Finals in 2025, their experience in Paris—both from the 2025 NBA Finals and the 2026 EuroLeague Finals—could give them a home-court advantage. Monaco’s visit to Boston next year may also lead to increased collaboration between the two leagues.
