Olympiacos has officially secured the signing of Dominican guard Jean Montero, who joins the Greek powerhouse on a three-year contract running through 2029. The move marks a significant roster shift in European basketball, as Montero transitions from Valencia Basket to the EuroLeague contender following the activation of his release clause.

The formal announcement from Olympiacos confirms that Montero will remain with the club for the next three seasons.
Montero’s departure from Valencia Basket follows a period of significant personnel turnover for the Spanish side.
Valencia Basket Personnel Adjustments
While the club confirmed the departure of its star guard, it has also moved to address the vacancy by integrating other pieces, including the addition of forward Dylan Osetkowski.

The financial mechanics of the deal—specifically the payment of the buyout clause—allowed Montero to bypass the remaining duration of his contract in Valencia.
Broader EuroLeague Offseason Context
Montero’s signing is one of several high-profile moves currently reshaping the EuroLeague landscape. For instance, reports have linked other established players to various European destinations, including Anadolu Efes and Panathinaikos, as the continent's top teams finalize their squads ahead of the preseason.
