Takehiro Tomiyasu has been made official as an Arsenal player.

The Japanese have been rumored since the morning that he will be made official as an Arsenal player.

Edu, Arsenal’s sporting director, was in talks with Bologna to sign the 22-year-old on the morning of the final day of the transfer window.

The deal was formalized only after the departure of Hector Bellerin to Real Betis.

Arsenal have bought Tomiyasu for 20 million euros and 3 million bonuses.

He underwent medical tests in Italy until his agent signed his contract in London in the late hours of the night.
