Japan international Yoshinori Muto has rejected a move to Chelsea in favour of joining Mainz, per Kyodo News (via the Daily Telegraph).
Muto had been the subject of a £4 million offer from Chelsea, per Sports Nippon (h/t James Orr of The Independent), and he had been considering the chance to join the Premier League champions.
But he now looks likely to head to the Bundesliga instead, and a move to Mainz would see him link up with his fellow Japanese striker Shinji Okazaki.
