The Turkish youngster is said to be scouted by the Gunners for a while now.
The 21-year-old joined the Italian side back in 2017 from Bashaksehir.
He quickly established himself as one of the promising talents in the league.
The winger has scored six goals and provided nine assists this season across all competitions.
At the international level, Under has netted four goals in ten appearances.
Why should Arsenal sign?
As the future of Mesut Ozil remains tentative and Aaron Ramsey’s exit is looming, Unai Emery should pursue the Turkish prospect to bolster the attacking options.
Under’s contract is due till 2022 and the Seria A side is persistent in keeping the young talent.
The Gunners are having a fluctuating season so far. However, the draw against Tottenham followed by the huge win against Manchester United has put the North London side back in top four.
The only signing made by the Gunners during the January transfer window is Denis Suarez from Barcelona.
They are limited to spend £40million alone in the summer owing to financial difficulties . But the chances could be maximized if Emery’s men were able to qualify for the next season’s Champions League.
The Gunners will play against Rennes in Europa League’s round of 16 second-leg on Friday.
