The forward – who has signed a pre-contract agreement with Rangers for next season – and her Glasgow City teammates play Wolfsburg in the last eight tonight (Friday).
The Scottish Women’s Premier League title holders are the only part time side left in the tournament and are on the hunt for their biggest triumph in their Champions League history.
Kirsty said: “It will be a great opportunity for us to play against a very strong, experienced Wolfsburg side. I would say the pressure is mainly on Wolfsburg due to their dominance in women’s European football over the past ten years but we will give it our all and you never know what can happen in 90 minutes.
“To make it this far in the tournament is an achievement in itself so we’re all really to go out and enjoy the game as much as we can.”
Glasgow City reached the quarter-final after defeating the Czech side Chertanovo Moscow in the round of 32 with 5-1. In the round of 16 Glasgow’s narrow defeat of the Danish team Bröndby took them through after penalties.
Instead of the original two leg tie, the closing stages of the competition has a condensed format with a single leg match against the German champions taking place at the Anoeta Stadium in San Sebastian behind closed doors.
The match will be shown live on BBC Alba with a 5 pm kick-off.
