Karl Hein is a member of a pretty unique club. Aged just 18, he was yet to make a senior club appearance when he was handed his full international debut in Estonia’s 1-0 UEFA Nations League defeat to Georgia.
As is to be expected from the calm yet fiercely determined goalkeeper, Karl took the experience fully in his stride – and, under the guidance of former Gunner Mart Poom, the 6ft 4in 20-year-old has made his country’s No1 shirt very much his own since.
Karl has developed serenely at club level too and was rewarded with an Arsenal debut in the recent Carabao Cup tie against Brighton & Hove Albion, before keeping a clean sheet in our Dubai Super Cup win over Lyon – making four penalty saves in the post-match shootout.
