Brittany Held shared her Hungarian adventure with Instagram followers earlier this week.
And while Polster will be in the thick of gruelling Gers training, Held’s week has been anything but.
She shared a snap from one of the Hungarian capital’s famous baths, the Szechenyi thermal bath.
With a woman she described as her best friend, Held donned a yellow bikini in cool temperatures of around 14C.
The American wrote: “Travelling and getting lost in beautiful places, together.”
“I want to play, I don’t want to just be working under him I want to play for him, so the main thing and the main goal is to get on the pitch at some point”
But she’s certain to be needed back in Glasgow for Sunday’s Old Firm clash.
She has already established herself as a firm Gers favourite thanks to her vocal Rangers support through her Instagram account.
Held regularly appears at games to cheer on Steven Gerrard’s side.
Polster is yet to make his Gers debut due to injury, and says he’d love to make his first appearance against Celtic.
He told Daily Record: “I want to play, I don’t want to just be working under him I want to play for him, so the main thing and the main goal is to get on the pitch at some point.
“I don’t know when the time will come. I don’t think the results will change how the manager decides the line-up.
“For me, it’s just showing that I can play at this level week in, week out in training and focusing on myself.
“I’ve worked hard and I feel good so when the time is right, I’ll be ready.”
He continued: “I would love to be a part of it. Obviously it’s a big match.
“I haven’t even seen it live. I was away when we played them at the end of the year.
“It’ll be quite a day. The expectation is always the same, you want to beat them.”
Rangers currently lie 10 points behind the Hoops in the Scottish Premiership.
If they lose, their title hopes will be all but over.
And Celtic will be desperate to avenge the 1-0 loss they suffered at Ibrox in December.
