Arsenal have agreed a £19.8m (€23m) deal for Bologna defender Takehiro Tomiyasu with Gunners right-back Hector Bellerin close to joining Real Betis on loan.
Japan international Tomiyasu is now set to have an Arsenal medical with personal terms not expected to be a problem.
The 22-year-old can play both centre-back and right-back and had attracted interest from Tottenham earlier in the transfer window.
Tomiyasu has made 64 appearances for the Italian side and came on as a late substitute in Bologna’s 0-0 draw at Atalanta in Serie A on Saturday.
Arsenal had also been keen on signing Barcelona right-back Emerson Royal, but the 22-year-old’s preference was to move to their north London rivals Spurs.
Tomiyasu’s potential arrival comes with Gunners right-back Bellerin having a medical in London ahead of a loan move to Real Betis with an option to buy.
