The Gunners will complete the signing of the England international once he returns from holiday
Arsenal are closing in on the capture of Ben White after having a bid accepted by Brighton for the centre-back.
The Gunners have been locked in talks with the Seagulls for weeks over the 23-year-old and had already seen two offers knocked back.
But a breakthrough in negotiations on Friday saw a £50 million ($69m) bid accepted, with Arsenal now being given permission to finalise a deal with the England international.
