Arsenal are eyeing Napoli defender Kalidou Koulibaly.
According to Calciomercato.com, the Gunners are keeping tabs on Koulibaly.
The London club are poised to recruit defenders this summer after failing to land reinforcements during the January window.
The Premier League side sent a team of scouts to watch Koulibaly in Napoli's Europa League clash with RB Leipzig on Thursday night. Koulibaly is valued at around £40million - but the price is only set to rise due to market inflation.
