#3 Kalidou Koulibaly (Napoli)
Koulibaly is targeted by the Arsenal club together with team-mate Jorginho. The latter is set to join Manchester City after confirmation from his agent. Arsenal is not the only Premier League club interested in signing Koulibaly, with Chelsea and Liverpool keen too.
Having vast experience in Serie A, he could be a promising defender in the Premier League. Standing at 1.93m, he will be one of the tallest defenders if Arsenal signs him. Arsenal has struggled to defend set-pieces this season and one reason was that of the lack of aerial strength. With him around, he will be able to mark the taller opponents surrounding him and provide more stability at the back.
One great thing about Koulibaly is his great display of fitness throughout the many seasons. Arsenal will require defenders who can play on a weekly basis and recover quickly from fatigue. At 26 years of age, it is really his prime time to make a move to the Premier League and Arsenal could convince him.
