Rigondeaux is regarded as the best fighter in the division and is yet to lose as a professional, but Galahad - who has recently returned from a drugs ban - is keen to meet the Cuban in Manchester on October 29.
The 26-year-old told World Boxing News: "While other fighters and world champions avoid Rigondeaux, I want him.
"If you're a fighter you should want to beat the best to become the best. Rigondeaux's the number one in the super-bantamweight division and is the man to beat, he's the main man and I'm in boxing to be recognised as the best.
"How do I beat him? Father time catches up with everyone, he's getting on a bit now and I have youth and desire on my side. Listen, he's a fantastic boxer there's no denying that, but as you get older the timing and speed begins to slow down."
Galahad is currently unbeaten in 20 fights and has previously held the British, Commonwealth and European titles.
