Kerr looms as the key player in Saturday's W-League grand final against Sydney FC at Jubilee Stadium.

The 25-year-old scored a stunning hat-trick in last week's 4-2 semi-final win over Melbourne Victory, and will have a target on her back when she lines up against her former Sky Blues teammates on Saturday.

Kerr has taken the football world by storm in recent years, starring on the international stage with the Matildas, as well as dominating the domestic leagues in America and Australia.

But her dominance has come at a cost - a long holiday drought.

Kerr says she has only had a two-week break over the past year, and can't even remember when her last holiday trip was.

Suffice to say she is ready for a break - a luxury she won't allow herself until after the World Cup in June-July.

"I've told everyone that if we win the World Cup I'm having some time off and going around Europe," Kerr says.

"I can hopefully do the Greek Islands and Croatia. But that's only if we win it."

There's growing talk Kerr will join a European club later this year instead of returning for another W-League campaign.

But the proud West Australian says no decisions have been made.

Instead, Kerr is fully focused on guiding Glory to some long-overdue silverware.

Glory lost W-League grand finals in 2014 and 2017.

Kerr was sidelined with a serious knee injury when Glory lost the 2014 decider 3-1 to Canberra United.

And Kerr was well restricted during the 2-0 grand final loss to Melbourne City two years ago.

Kerr has a trophy cabinet bulging with individual awards, but she would trade them all for a W-League title with Perth Glory.

"This would top everything. This would be right up there with winning the Asian Cup with the Matildas," Kerr says.

"It would be a dream come true. I'd give in all the medals I've won over the last few years to win this.

"I've been dreaming of this for 10 years. I can't imagine what the feeling would be like."

The excitement of being in the running for a title is helping stave off any tiredness after her hectic recent years.

"It does get mentally draining sometimes," Kerr says.

"But even when I was on a two-week break, I couldn't wait to be playing again. It's a bit of a tug of war with my mind and what I want to do.

"It's tough, but I love what I do, so I'm lucky and I don't take it for granted. There would be a million people wishing they could do what I was doing."
