Ritchie played for Bremner's Leeds side in the Eighties so knew the Scot well and ahead of his return as Huddersfield Town manager.
He told the Yorkshire Post: "It will be an emotional day for everyone and particularly Billy's old team-mates such as Eddie Gray, who I know works for local radio. To be honest, I had not realised it was 10 years ago that Billy died. He was my manager at Leeds for a few years and a very bubbly character. He was what I would call a 'player's manager'.
"He loved the banter with the lads and he was never short of a quick remark. He also joined in with the five-a-sides, and let's just say he kicked a few people during them.
"Billy built a good side that came so close to winning promotion and reaching the FA Cup final. But we just came up short in both."
Ritchie left Elland Road for Oldham Athletic a few weeks after Bremner's Leeds had been beaten in the Second Division play-off final in 1987.
