Barcelona B forward Gai Assulin wasn't named in Israel's Under-21 national squad on Monday after he decided training with the team will hurt his preparations for next season. The 18-year-old's father spoke to team administrator, Eli Rosen, and said his son needs to rest ahead of next season and therefore will not be joining the team for of its European Championship qualifier against Bulgaria next Wednesday. Rosen told Assulin that snubbing his call-up could hurt his future international career, but the player, who became Israel's youngest ever international last March, decided to remain at home nevertheless. "This is disappointing. It's a shame the Assulin family has made this decision," team coach Moti Ivanir said. "It's hard for me to believe that Gai refuses to play for the team as he's giving his all when playing for it in the past. Gai should be an example to many youngsters who want to see him play for the national team."
