The London club; Arsenal have agreed a deal in principle for the £50m transfer of Brighton & Hove Albion defender Ben White.
White who went on a number of loans from the Seagulls, including to Leeds' Championship title-winning side in 2019-20.
White's performances for Leeds attracted the attention of many leading clubs and prompted Brighton to secure him on a new four-year contract last summer.
That deal put the Seagulls in a strong negotiating position this summer and it is understood they rejected two bids from the Gunners before agreement was finally reached amid interest from other Premier League clubs.
White is on holiday so the transfer, including his medical, will not be completed until he returns.
