Olympiacos 'Almost Full Roster' for New Season: Jean Montero Starts Training Immediately Ahead of Crete Tournament

Olympiacos is entering the 2026-2026 season preparation phase with disciplined pace and clear confidence. Head coach Georgios Bartzokas stated that the Greek team has nearly the full roster ready, while new signing Jean Montero - born in 2026 - officially joined on September 2 and began his first training session on September 3. This event is not just a routine transfer but a key signal for the Crete Tournament starting September 4-6, where Olympiacos will face Fenerbahce, Armani Milan, and Red Star. This is the chance for Bartzokas to test immediate chemistry between players, especially blending his ball-movement system with Montero's attacking style. In the context of EuroLeague 2026-2026 after summer break, Olympiacos - a team often in the top 4 - focuses on team cohesion. According to official sources, coach Bartzokas had almost all players return, including key players like Thomas Walkup, Kostas Sloukas, and Alexis Fall. Minor absences due to international schedule or personal reasons are insignificant, creating a major strategic advantage for lineup assembly. Bartzokas can conduct joint sessions and test lineups from the first week without worrying about sudden injuries or absences. This differs from many European teams struggling with injury issues during transition. The biggest event is Jean Montero officially joining Olympiacos. Born in 2026, Montero brings youth and attacking energy at guard position. Before Crete, Montero joined some solo sessions and was immediately assigned to test in joint sessions by coach Bartzokas. On September 3, Montero joined the first team training, showing high priority from the coaching staff. This is not random but from Olympiacos's long-term strategy: instead of relying only on experienced players like Walkup or Sloukas, the team is adding young blood to maintain competition in both phases. Deeper analysis on Montero factor: This player has a signature attacking guard style with good scoring and situation creation. In 2026-2026 at Valencia, Montero showed value at 13-15 points per game and 3-4 assists, with average shooting efficiency around 55%. However, moving to EuroLeague requires adaptation to fast pace, high physical intensity, and collective play. Olympiacos with Bartzokas's strong movement system needs a guard who can control ball and create space. Montero is ideal to fill this gap, especially since he has FIBA experience with Dominican Republic, helping him quickly adapt to European physicality. Crete Tournament will be the first stage to test this blend. Teams include Fenerbahce with strong pressing, Armani Milan with high speed, and Red Star with experience and youth mix. Olympiacos will have chances to test multiple lineups, from Montero starting as primary guard to bench to create second-half pressure. Bartzokas can use near-full roster availability to build different scenarios, from fast attack to more complex tactics. This not only helps the Greek team get used to match pace but also allows coaches to adjust timely before the crucial phase. From data perspective, Montero is a long-term investment for Olympiacos. This young player represents the trend of prioritizing youth and athleticism at guard, where current pillars like Walkup and Sloukas are aging. Adding Montero not only boosts scoring but also adds rotation diversity. Coach Bartzokas can balance using Montero as creative substitute and keeping lead for experienced players. This is crucial to avoid single-point dependency, a common risk in teams adding young players. On salary cap aspect, Olympiacos is utilizing new EuroLeague 2026-2026 soft cap and luxury tax rules. Signing Montero at reasonable level shows financial commitment to competitive roster. However, with new rules, Olympiacos must carefully consider future contracts to avoid tax pressure. Long-term deals with young players like Montero will help manage budget effectively while maintaining competition. In league landscape history, European teams like Olympiacos use preseason to test cohesion. Crete Tournament with four teams creates high competition environment, helping Olympiacos quickly assess Montero adaptation. Compared to previous seasons where Bartzokas adjusted more lineups, this year the Greek team has big advantage due to full roster availability. This helps coaches focus on tactical training rather than personnel worries. Contrarian angle: Many may doubt Montero fit due to style contrast, but ACB and FIBA data show high adaptability. Veteran core like Walkup still need roles, avoiding single point on Montero. Preseason does not predict regular, but full squad is big advantage. If Montero slow, Olympiacos still has Sloukas lead. Long-term youth value outweighs immediate risk. New salary cap may constrain future moves, but Montero buy-low potential. Overall, this preseason sets stage for open contention window but narrowing. Takeaway: Olympiacos entering season with momentum. Watch Crete results for Montero role definition. Question: Will Montero become key rotation or developmental project? Next domino: Integration speed in first EuroLeague games. This prepares Olympiacos for playoff push while building future.
