Scottish featherweight Nathaniel Collins is on the cusp of a career-defining moment, and he's left absolutely nothing to chance. After a grueling training camp he describes as putting his body "through hell and back," Collins is ready for his high-stakes rematch with Spain's undefeated Cristobal Lorente.

The stakes couldn't be higher this time around. Their first bout in Glasgow last October ended in a split draw, the only blemish on Collins's impressive 18-fight professional record. The upcoming clash at the Hydro Arena is no ordinary sequel; the winner will be crowned the official mandatory challenger for the prestigious WBC featherweight world title.

To prepare for this pivotal moment, Collins sought out the ultimate test: world-class sparring in Los Angeles. "We took ourselves away for eight, nine days for sparring with world champions," Collins revealed. He shared the ring with former featherweight champion Mark Magsayo and other elite fighters, experiencing an intensity he calls "exceptional."

"The sparring out in America... they don't know you, they don't care about you, they are coming to take your head off," Collins said, highlighting the unforgiving environment that sharpens a fighter's edge. This level of preparation underscores the monumental step a world title shot represents in a boxer's journey.

Now 30 and with over 14 years in the sport, the man nicknamed 'The Nightmare' feels his time is now. "It is definitely time to break through and become the person that I think I should be," he stated, his focus squarely on securing the mandatory challenger spot and inching closer to his ultimate dream.
