But Alker denied making any homophobic comments and insisted he had only hit extremely drunk Mr Causer in self-defence.
He blamed the fatal attack on his friend James O’Connor.
O’Connor, 19, formerly of Huyton, now of The Brow, Runcorn has already admitted murder.
Mr Causer died in hospital from massive head injuries eight days after the attack on July 25 last year.
Mr Justice King released Alker from the dock. He will fix a date later to sentence O’Connor and Michael Binsteed, 18, Evelyn Avenue, Prescot, for perverting the course of justice.
