Mikel Arteta has confirmed that the £540,000 signing of Hertha Berlin defender Omar Rekik will be announced 'very soon'.
The news comes shortly after the centre back took part in training with Arsenal's U23 side on Wednesday.
Arteta has described his first signing of the January transfer window as a 'young talent with a very bright future'.
Arsenal had reached a deal with Hertha Berlin to sign Rekik for £900,000 on the final day of the summer transfer window. However, the switch was not signed off in time forcing, both clubs to hold off until January.
