Arsenal youngster has gone on a season-long loan to Bolton, according to various sources (including Young Guns and Arseblog). According to Jamie Sanderson's tweet, Miyaichi will not be eligible to play against Arsenal in tomorrow's match for Bolton (which honestly he probably wouldn't have anyway, but still).
Miyaichi has made only two first team appearances for Arsenal this year, both in the Carling Cup. He's also started fairly regularly in the reserves side, but has been inconsistent there and has failed to break back into the first team in the way fellow young winger Alex Oxlade-Chamberlain has. Miyaichi follows in the footsteps of Jack Wilshere (RIP) who was also loaned to Owen Coyle's side in January of 2010 (and hopefully he'll also follow in his footsteps in regards to the next year of his career, but maybe not the year after that).
This is a good move for the youngster, who really probably needs consistent first team football to properly develop as a player. The reserve team isn't quite the same thing, and after impressing at Feyenoord last year but then losing momentum after an injury this year, this might be just the prescription Ryo needs to get back on track. Bolton face Chelsea, Manchester City, and Tottenham Hotspur still this year, so Miyaichi may get to play against some stern competition; either way, the Premier League is a whole different monster than the Eredivisie, so we'll see if he can handle it yet (and the pressure of a relegation battle).
Miyaichi joins Emmanuel Frimpong and Niklas Bendtner in the ranks of Arsenal players on loan with Premier League teams.
