Arsenal have agreed to sign Hertha BSC defender Leander Siemann following a trial. The German centre back will complete the transfer in the summer.

Siemann joined Arsenal on trial in February, as Young Guns revealed. A regular for Hertha’s Under 16’s, he was set to leave the club in the summer, to spend a year in London studying. However, a family friend recommended him to Liam Brady, and the 15-year-old impressed during a week long training stint.

The six foot two inch youngster is noted for his powerful and physical approach. At home at either centre or right back, Leander has signed a three-year-contract, and told German agency ‘Bild’ that the move is a ‘dream come true’.

Arsenal have agreed a compensation package worth €250,000.
