Portsmouth have added Brighton goalkeeping coach John Keeley to their backroom staff.
The 45-year-old will begin his new role with the Seagulls' South Coast neighbours in July.
He was Brighton's goalkeeper between 1986 and 1990 before becoming kit-man and goalkeeping coach in 2001.
He said: "It's an offer I couldn't refuse. I've got a lot of time for Brighton but sometimes you get an offer that you simply cannot turn down."
