Mikaela Mayer has no desire to remain in one place.

After recently heading up to the lightweight limit of 135. she is now heading up junior welterweight to face Silvia Bortot on Saturday night in Manchester.

Her fight will be part of the undercard to the grudge rematch between Liam Smith and Chris Eubank Jr. at the AO Arena.

Mayer has no desire to stay at 140.

She intends to head up to the welterweight limit of 147-pounds to purse a clash with IBF world champion Natasha Jonas.

And she hopes to get that fight in the very near future.

"Natasha Jonas is at the top of my list because it's the most realistic, immediate fight for me," Mayer told Sky Sports.

"Hopefully we can get that fight done sometime in December or early January. That's where I want to go immediately after this fight. I'm not sticking around at 140-pounds, I'm going to 147-pounds after this fight. I'd like to step right into a world title fight because that's where I believe I'm at."

Before she can think about Jonas, Mayer wants to make a statement against former European champion Bortot.

Once that statement is made, Mayer will place her full focus on securing the biggest fights possible at welterweight.

"I'm more determined and motivated now than ever," Mayer said. "I want to show my boxing skills. I want to show my power and my strengths from the outside. Just a little bit of everything, put it all together. But I really want my strengths to come through."

"It's just to stay busy, gradually get ready for the 147-pound weight class that I plan to go to. And yes, we have a plan. So bigger fights are coming. I have the experience, I have the skill, I have the size to be fighting at a more comfortable weight. Now training at this heavier weight, I feel so much better, and I enjoy training more because it's not so exhausting. It's not so mentally taxing. My body feels good. I feel energized. As a result, I'm reaping the benefits of all my hard work."
