Prior the 2017–18 season, Žalgiris reached an agreement with club sponsor Avia Solutions Group to guarantee private flights for the team during away games in a refurbished business-class Boeing 737. The off-season work began just a week after winning the LKL championship, when breakout player Brock Motum signing with Anadolu Efes S.K.. To replace Motum, Žalgiris signed Aaron White, who had played a season with Zenit Saint Petersburg. Léo Westerman signed with CSKA Moscow, and was replaced by talented guard Vasilije Micić. To replace Seibutis, Žalgiris originally signed Royce O'Neale, who terminated his deal just weeks later to sign with the Utah Jazz. Žalgiris then signed Axel Toupane to replace him. Because center Robertas Javtokas announced retirement and the loan of Augusto Lima ended, Žalgiris signed Brandon Davies of AS Monaco Basket in the center position. The most-shocking departure came at the end of June, when breakout point guard Lukas Lekavičius signed a contract with Panathinaikos. Needing a new point guard, Žalgiris signed Dee Bost, also of AS Monaco. Coach Jasikevičius also re-signed with Žalgiris, while the retired Javtokas became the new sports director of the team. On September 22, Žalgiris played a game in London against Polski Cukier Toruń, which Žalgiris won 87–61. Žalgiris won the King Mindaugas Cup for the second year in a row, defeating Lietuvos rytas 81–62 in the finals. Edgaras Ulanovas won the tournament MVP for the second straight year.
