German side Mainz signed FC Tokyo striker and former Chelsea target Yoshinori Muto on a four-year contract.
Muto is said to have rejected a Chelsea offer because he was scared to not have regular game-time.
Jose Mourinho revealed during a press conference a couple of months ago that his club were keen on signing Muto because of ‘commercial interests’, since Abramovich’s club in February closed a commercial deal with Japanese company Yokohama Rubber, who will be sponsor t-shirt for the next five years, replacing Samsung.
Muto, 22, has scored nine goals in 14 appearances in the J-League’s top flight this season; last season he scored 13 goals, a record-tying mark by a J-League rookie.
He has been capped 11 times by the national team, scoring one goal.
He is considered the next Japanese football star.
