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.
Arsenal have always been confident of striking a deal for White , who was the club’s priority defensive target this summer.
Despite having two earlier bids rejected, talks with Brighton always remained amicable, with the ongoing negotiations centring around the structure of the transfer.
Arsenal had previously indicated to Brighton that they were willing to meet their £50m valuation, but what had to be agreed was the exact structure of the deal and the various clauses and bonuses that would be included.
Full agreement between the clubs was reached on Friday, with Arsenal now able to finalise personal terms with the player ahead of his move to north London.
Will the deal be completed quickly?
There could be a slight delay in completing the transfer, as White is currently away on holiday following the conclusion of Euro 2020.
All players who were involved with England at the tournament have been given three weeks off, although White is expected to cut that short at some point to finalise his transfer and undergo a medical.
Arsenal are currently in Scotland at a training camp and will travel back to London after the game with Rangers on Saturday before flying to America early next week to take part in the Florida Cup.
White will not, however, be involved in the trip to the United States.
