Fabrizio Romano has dropped an exciting Arsenal transfer update about the terms of their deal to sign Takehiro Tomiyasu on deadline day.

What's the story?

The Gunners rounded off their summer transfer window by signing the Japan international from Serie A side Bologna, and now Romano has revealed the cost of the deal.

Writing on Twitter, he revealed: "Official and confirmed. Takehiro Tomiyasu joins Arsenal on a permanent move from Bologna for €18m. Paperworks signed, deal completed. #AFC #DeadlineDay"

Arsenal fans will be buzzing

At just €18m (£15.5m), Tomiyasu certainly isn't the most expensive player Arsenal have brought in this summer, but once again, he fits the bill in terms of the kind of profile of player they are looking for: young, lots of potential and with versatility too.

The Japanese ace is just 22, and can play anywhere across the back-line and in holding midfield too, and he could quite feasibly play as a right-back or as the right-sided centre-back in a back-three if Arteta chooses to go down that route.

His teammate at the Stadio Renato Dall'Ara, Mitchell Dijks, dubbed him "very strong" and a "true Japanese warrior" at a press conference, via Tuttosport.

In fact, speaking about the defender’s potential, former Japan coach Alberto Zaccheroni said: “He is a complete player and Bologna got a real bargain with Tomiyasu. He’s a good player and was compared to Maya Yoshida, who has been playing in Europe for a decade. He’s got the quality to be a real star.”

And, speaking after confirmation of the signing, Arteta himself said: "Takehiro is a strong defender with good experience in Serie A and at international level. He’s a versatile defender with great defensive qualities, high technical ability and composure on the ball. He will be an important member of our squad. We look forward to Takehiro joining up with us when he returns from international duty."

Romano's update that Tomiyasu will just £15.5m, especially in this market where the Gunners spent £50m on someone like Ben White, is sure to have Arsenal fans buzzing.

Not only does the low fee ensure the pressure and scrutiny on the Japanese defender is much lower than the pressure on White, but it also allows the Gunners to chance to make a genuine profit on him if he were to really develop and another side comes in for him in the future.

A win-win all round.
