The jerseys are now being auctioned online by the Royal British Legion, with all monies raised going to the Poppy Appeal.
Two service men from the RAF, Sergeant John Bullock and Corporal Jeremy Ambrose, received the special shirts alongside Bill Martin, RBL County Secretary for Merseyside and West Lancashire.
All 18 items are now available to bid for on eBay and all funds raised will help the Royal British Legion support today’s generation of armed forces families and veterans, whether living with an injury or illness, coping with bereavement or finding employment.
Alexander-Arnold said: “The team was extremely proud to wear the poppy, to show our respects to the armed forces for the amazing work that they do and the sacrifices they make to serve our country.
