The Venezuelan is a three-weight world champion but with the WBC Diamond, Ring Magazine and Crolla's WBA title on the line, he has suggested that the Manchester bout could define his illustrious career.
The 31-year-old told reporters: "We are ready and come Saturday night - we are taking all of the belts.
"Thanks to everyone for the warm welcome. This is the most important fight of my career."
Linares has won 40 of his 43 fights as a professional, while Crolla has 31 victories from 38 outings.
