O'Sullivan fighting back from the ropes, but she faces mammoth task winning back public support
These days, Katie Taylor is a lean, mean fighting machine. Since moving to the professional ranks, her much-touted 'killer instinct', critical to survival in the loneliest of arenas which is the boxing ring, has become even more deadly and focused.
In her amateur phase, a fierce singularity of purpose was her most potent weapon; she knew that in the fight game, the merest hint of self-doubt can spell disaster. Any perceived psychological weakness on her part would be seized on by an opponent, who would split her defences wide open.
As she chases world title affirmation, we can only wish her well in the without-pity world of professional boxing, and that she achieves whatever golden standard she desires. Hopefully she will also garner a good whack of cash along the way, before hanging up her gloves while she is still ahead.
