Celtic Boys Club founder Jim Torbett has been jailed for six years after being convicted of sexually abusing three boys over an eight-year period.
Torbett, 71, was found guilty after a trial at the High Court in Glasgow. He had denied the charges.
His victims included youth players Kenny Campbell and Andrew Gray, who had waived their right to anonymity.
Lord Beckett told Torbett: “Yours is some of the most corrupting behaviour I have ever heard of in these courts.”
He added: “Your depraved conduct towards innocent children has blighted their lives.”
Jurors had heard that Torbett, of Kelvindale, Glasgow, targeted the schoolboys between August 1986 and August 1994.
Mr Gray died last year, but statements he gave to police before his death were read out during the trial.
The third victim said he had been abused as a five-year-old when he visited the Trophy Centre, which was owned by Torbett.
There were tears in the public gallery as the verdict was announced.
