Arsenal are to sign the Japan striker Takuma Asano from the J-League club Sanfrecce Hiroshima. The 21-year-old made his international debut in August last year and has made five appearances. The forward is expected to be named in Japan’s squad for the Olympic Games in Rio. “Takuma is a talented young striker and very much one for the future,” Arsène Wenger, the Arsenal manager, said. “He has had an impressive start to his career in Japan and we look forward to him developing over the next couple of years.” The forward boosts Arsenal’s attacking options after their pursuit of Jamie Vardy ended in failure. “Vardy has decided to stay at Leicester and good luck to him,” Wenger said. “He came late to the game and in fairness Leicester bought him from Fleetwood and he has been successful. He is 29 and he has chosen to stay at Leicester. You have to respect that.” Asano, whose transfer is subject to a medical, is expected to train with the first‑team squad. He becomes the third Japanese player to play under Wenger at Arsenal, following the midfielders Junichi Inamoto and Ryo Miyaichi. He joins Granit Xhaka in signing for Arsenal this summer.
