The main concern for Ayala stems from the Hydro's last big boxing bout.

A source of dread fuelled by Josh Taylor's controversial victory over Jack Catterall in the same venue in February.

"I saw that fight... wow," the challenger said. "I'm a little bit worried about the judges.

"Whether you believe it or not, I know for a fact there's a bias, even if it's subconscious. It won't be the first or the last [decision like that]. I just have to convince."

The atmosphere is bubbling away very nicely indeed here after Nathaniel Collins' gruelling 12-rounder with Jacob Robinson.

Collins retained his Commonwealth title via unanimous decision. The 4,500-strong crowd at the Hydro will be hoping for similar in the next bout...

BBC Sport Scotland's Nick McPheat sat down with Rankin earlier in the week.

This historic nature of the occasion is not lost on the fighter.

"There are younger girls coming along to this fight. They'll be thinking: 'That'll be me one day'. That's what it's all about, inspiring them. I'm going to put on a show for them. That's what I'm here for."

In the penultimate fight of the night Scotland's Nathaniel Collins remained undefeated as he emerged victorious from a 12-round battle against the Welsh fighter Jacob Robinson.

The bout was for the Commonwealth Featherweight Championship, and Scot Collins won via a unanimous decision to retain his title.

Can Rankin keep the Scottish victories rolling?

Mexican challenger Ayala, who boasts a better win record and far superior knockout rate, stands in the way of Rankin's title defence. But the 33-year-old, in her first world title bout, will still enter the ring as the underdog.

The vast majority - if not all - of the Glasgow crowd will be roaring in favour if the champion, but the relaxed and confident Ayala is "here to shock Scotland".

"I don't hear the crowd," she tells BBC Scotland. "I'm just attuned to myself and to my corner. I feel the strongest I've ever felt. I want this so badly and I'm going to show it in there.

"We have a plan, but if the plan doesn't work, we're going to go all out 'Viva Mexico'. We're going to brawl it out. I'm going to leave everything out there."

Rankin has already provided some a historical boxing moment for the nation when she became Scotland's first female boxer to win a world title.

From pulling pints next door to tonight’s venue in the SECC, to topping the bill at the Hydro this evening, it has been a remarkable rise for the fighter who is also a professional bassoonist.

Tonight’s bout is historic in nature too as it is the first female-topped boxing bill to take place in Glasgow’s spaceship looking attraction.

Rankin has fought 16 times and boasts a record of 11 wins and five losses.

Four of her five losses have come via decision with one knock-out on her record too.

Alejandra Ayala will likely prove to be a stern test for Rankin and travels to Scotland determined to upset the odds and win the belts.

Mexico has a rich and proud boxing heritage and Alejandra is determined to join the long list of world champions.

If Ayala wins tonight, she would become her country's first Super-Welterweight champion.
