Japan international Takuma Asano was signed for Arsenal during Arsene Wenger's time as manager but never made an appearance.
Just 21 years old at the time, Asano was signed with a promising reputation but his career at the Emirates Stadium didn't exactly go to plan. Speaking about the signing after missing out on a move for Leicester star Jamie Vardy, Arsene Wenger said: "Takuma is a talented young striker and very much one for the future."
The Japanese forward was not granted a work permit resulting in him heading to Germany to play for Hannover and Stuttgart on-loan. Three years after joining the Gunners, Asano left for Partizan Belgrade on a permanent deal and, now 28 years old, he is back in the Bundesliga with Bochum.
