Arsenal is close to wrapping up the €20 million signing of Jakub Kiwior from Spezia.
Kiwior, a left-sided centre-half, is set to undergo medicals this weekend, according to Fabrizio Romano.
The 22-year-old will then put pen to paper on a five-and-a-half-year contract.
Arsenal sees him as a player capable of deputising for Gabriel Magalhaes.
With Rob Holding almost certain to depart in the summer, the Premier League leaders are looking at maintaining a squad with five high-quality central defensive options.
Kiwior joins Gabriel, Ben White, William Saliba and Takehiro Tomiyasu as options available to Mikel Obi.
