Bennell, 64, was found guilty of indecent assault, buggery and attempted buggery against 11 victims -- all boys aged between eight and 15 -- in a complex trial in Liverpool in northwest England.
"Barry Bennell is a predatory paedophile who groomed and abused young boys who dreamed of a career in professional football," Jackie Lamb, from the Crown Prosecution Service, Englands state prosecutors, said after the trial concluded.
Bennell had already been found guilty on 36 charges on Tuesday, bringing the number of convictions from the trial to 43.
Revelations about the abuse suffered at the hands of Bennell triggered a wave of other former youth footballers to come forward and speak publicly for the first time about the ordeals they suffered.
