Former Arsenal defender Billy McCullough, who played 268 games for the club over eight seasons between 1958 and 1966, has died aged 90.
The left-back was also capped 10 times by Northern Ireland.
"All of us are thinking of his loved ones at this time," an Arsenal statement said.
He joined Arsenal from Portadown for £5,000 in September 1958 - the first signing for new Gunners boss George Swindin.
He made his debut in December but established himself as first-choice left-back the following season.
