"It is every boy's dream to play for this club and I can proudly say I have achieved this.
"I want to take this opportunity to thank everyone - from all the coaches that have helped me along the way, the staff, the many players I've played alongside while growing up but, most importantly, the fans that have showed constant support throughout my whole time here.
"I have so many unforgettable memories and experiences that I'll forever be grateful for, but I personally feel now is the right time for me to move on and to start the next chapter of my career.
"I wish everyone at the club the very best and again thank you."
