Completed in the summer transfer window, Takehiro Tomiyasu's transfer to Arsenal was a significant move for both the player and the club. The Japanese international joined the Gunners from Bologna for a reported fee of around £19.8 million, bolstering Mikel Arteta's defensive options. Tomiyasu's versatility as a defender, capable of playing at right-back and centre-back, made him a valuable addition to Arsenal's squad.
