Hannover 96 can buy Takuma Asano for €3m in the summer according to a report from Germany.

The Japanese 24-year-old was signed for £3.6m from Sanfrecce Hiroshima in the summer of 2016 but has yet to make a competitive appearance for the club.
Instead, his time has been spent on loan in Germany, first with Stuttgart before this season’s move to Hannover.
At this point, it’s hard to see him remaining an Arsenal player after the summer as the club look to get rid of as many players as possible to increase Unai Emery’s transfer budget.
According to an article in Peiner Allgemeine Zeitung, Hannover have an option to buy Asano for €3m, however, they do not indicate if this is a likely outcome.

Asano enjoyed a great pre-season with the Germans but his season has not developed as many would have hoped.
11 Bundesliga appearances have returned no goals nor assists while he is averaging just 56 minutes per game. His only goal contributions have come in the cup with a goal and an assist in his first game, but nothing since.
Asano is under contract with Arsenal until 2020 and with Raul Sanllehi determined to ensure no more players get into the last year of their deals with the club, Arsenal will either sell Asano or offer him a new contract, although that seems highly unlikely.
