It’s something that I’ve been working towards my whole life. I’ve just been trying to replicate my form and make the step up to the U21s. I’m on my way back from an injury, too so it’s about getting as much game time as I can with the U18s in the coming weeks and hopefully do well. Now it’s time for me to push on.
