The Academy hopeful is yet to celebrate her 16th birthday, yet she was a second half substitute alongside May Cruft, 14, and Sophie Black, 15, in tonight’s clash in Spain.
The trio have worked ever so hard in the heat in southern Spain this week and Boyce says she will use it as a taster of what could come later in her career.
Speaking to RangersTV after the match, the teenager beamed: “It’s an unbelievable feeling.
“Coming through the Academy and with all the support of the great coaches.
“I have had support from Jo, Jay [Bradford] and Craig McPherson which has been amazing.
“You need to pinch yourself sometimes, but it’s been great.
“The first-team is absolutely brilliant and I love being up.
“It’s a great test in every training session and you learn so much.
“Hopefully there’s more to come.”
As one of a trio of Academy players involved in the training camp, Boyce has been keen to catch the eye of the coaching staff ahead of the new campaign.
And learning off the plethora of international players in the Rangers ranks, she believes she will only get better when they opportunities do arise.
She added: “We trained at the start of the summer and I kept getting invited back.
“I felt like I was training well and it was a massive shock when I got the message about coming to Valencia.
“All the girls have been so supportive. Coming into a new team isn’t always easy, but they’ve helped us through every training session.
“It’s been a great opportunity and week of learning.
“A lot of the girls have more experience than I do, and it’s a massive help for my own game to get advice from them.
“Hopefully I can pass that on to some of the other Academy players.”
