On Instagram, the 22-year-old shared an old photograph of himself in an Arsenal shirt and wrote in the caption, "The time has come to say goodbye @arsenal. Having joined the Club in 2009 at 8 years old, I have so many incredible memories from over 15 years. I’ve made friends for life and owe so much to all the coaches I’ve worked with, teammates I’ve played with, fans who’ve supported me and everyone involved with the Club for helping me grow and develop into the person and player I am today. Arsenal will always be special to me and I hope to see them be successful in the coming years."
