Arsenal have struck a deal for Hertha Berlin defender Leander Siemann.

The Daily Mail says Arsenal have agreed a £220,000 deal for Siemann.

The 15-year-old German centre back spent a week on trial at the club last month and impressed coaching staff.

Siemann, who has been offered a three-year contract, said: "I've dreamt about being a professional, and Arsenal is a huge opportunity."

Hertha Under 16 coach Frank Vogel said: "He is dynamic, strong and good in one-on-ones."
